Understanding DSP Presets

DSP presets are saved configurations of audio processing parameters that can be instantly recalled to optimize a system for specific use cases. Think of them as complete audio "scenes" that adjust multiple parameters simultaneously.

Why Presets Matter

Consistency: Ensures optimal audio for each room usage scenario
User Experience: Simplifies operation for non-technical users
Efficiency: Reduces setup time between different meeting types
Optimization: Tailors processing to specific acoustic challenges

Planning Your Preset Strategy

Before diving into DSP programming, map out your preset requirements:

Common Conference Room Scenarios

Presentation Mode
- Single presenter at the front
- Audience questions from room
- Program audio playback
Video Conference Mode
- Far-end audio priority
- Echo cancellation optimization
- Microphone mixing for near-end
Hybrid Meeting Mode
- Mix of in-room and remote participants
- Balanced audio levels
- Advanced mix-minus routing
Training Mode
- Instructor mobility
- Multiple microphone zones
- Recording capabilities

Creating Conference Room Presets

Let's walk through creating presets for each scenario on popular DSP platforms.

Audio Parameter Optimization

Optimizing audio parameters for different room sizes requires understanding acoustic principles:

Small Conference Room (6-8 people)

Parameter	Value	Reasoning
Mic Gain	42-45 dB	Close proximity to participants
AEC Reference	-20 dB	Moderate echo path
Speaker EQ	Flat	Minimal room correction needed
Compression	2:1	Light dynamics control

Medium Conference Room (12-16 people)

Parameter	Value	Reasoning
Mic Gain	45-48 dB	Increased distance coverage
AEC Reference	-18 dB	Longer echo paths
Speaker EQ	2-4 dB @ 200Hz cut	Room mode compensation
Compression	3:1	More dynamics control

Large Conference Room (20+ people)

Parameter	Value	Reasoning
Mic Gain	48-54 dB	Maximum coverage needed
AEC Reference	-15 dB	Complex echo patterns
Speaker EQ	Custom per measurement	Significant room correction
Compression	4:1	Strong dynamics control

Acoustic Treatment Considerations

python

[object Object],
,[object Object], ,[object Object],(,[object Object],):
    ,[object Object],
    
    ,[object Object],
    rt60 = ,[object Object], * room_volume / surface_absorption
    
    ,[object Object],
    ,[object Object], rt60 < ,[object Object],:  ,[object Object],
        ,[object Object], {
            ,[object Object],: ,[object Object],,
            ,[object Object],: ,[object Object],,
            ,[object Object],: ,[object Object],
        }
    ,[object Object], rt60 < ,[object Object],:  ,[object Object],
        ,[object Object], {
            ,[object Object],: ,[object Object],,

Managing Multiple Scenarios

Implement a preset management system that handles transitions smoothly:

State Machine Implementation

python

        ,[object Object],.transition_time = ,[object Object],  ,[object Object],
        
    ,[object Object], ,[object Object],(,[object Object],):
        ,[object Object],
        ,[object Object],.presets[preset_id] = preset_config
        
    ,[object Object], ,[object Object],(,[object Object],):

        ,[object Object], new_preset_id ,[object Object], ,[object Object], ,[object Object],.presets:
            ,[object Object], ValueError(,[object Object],)
            
        old_config = ,[object Object],.presets.get(,[object Object],.current_preset, {})
        new_config = ,[object Object],.presets[new_preset_id]
        
        ,[object Object],
        transitions = ,[object Object],._calculate_transitions(old_config, new_config)
        
        ,[object Object],
        ,[object Object], param, (start, end) ,[object Object], transitions.items():
            ,[object Object],._ramp_parameter(param, start, end, ,[object Object],.transition_time)
            
        ,[object Object],.current_preset = new_preset_id
        
    ,[object Object], ,[object Object],(,[object Object],):
        ,[object Object],
        transitions = {}
        
        ,[object Object], key ,[object Object], new:
            old_value = old.get(key, ,[object Object],)
            new_value = new[key]
            
            ,[object Object], old_value != new_value:
                transitions[key] = (old_value, new_value)
                
        ,[object Object], transitions

Preset Scheduling

javascript

[object Object],
,[object Object], ,[object Object], {
    ,[object Object],(,[object Object],) {
        ,[object Object],.,[object Object], = dspController;
        ,[object Object],.,[object Object], = calendarAPI;
        ,[object Object],.,[object Object], = ,[object Object],; ,[object Object],
    }
    
    ,[object Object], ,[object Object],(,[object Object],) {
        ,[object Object],(,[object Object], ,[object Object],.,[object Object],(), ,[object Object],.,[object Object],);
    }

        } ,[object Object], ,[object Object], (event.,[object Object],.,[object Object],(,[object Object],)) {
            ,[object Object], ,[object Object],;
        } ,[object Object], ,[object Object], (event.,[object Object],.,[object Object],(,[object Object],)) {

        }
        
        ,[object Object], ,[object Object],;
    }
}

Testing and Validation

Comprehensive testing ensures your presets perform correctly:

Automated Test Suite

python

[object Object], ,[object Object],:
    ,[object Object], ,[object Object],(,[object Object],):
        ,[object Object],.dsp = dsp_device
        ,[object Object],.test_results = []
        
    ,[object Object], ,[object Object],(,[object Object],):
        ,[object Object],
        tests = [
            ,[object Object],.test_audio_levels,
            ,[object Object],.test_routing,
            ,[object Object],.test_processing,
            ,[object Object],.test_feedback_stability
        ]
        
        ,[object Object],
        ,[object Object],.dsp.recall_preset(preset_id)
        time.sleep(,[object Object],)  ,[object Object],
        
        ,[object Object],
        ,[object Object], test ,[object Object], tests:
            result = test(preset_id)
            ,[object Object],.test_results.append(result)
            
        ,[object Object], ,[object Object],(r[,[object Object],] ,[object Object], r ,[object Object], ,[object Object],.test_results)

        }
        
        ,[object Object],
        ,[object Object],.dsp.inject_test_signal(-,[object Object],, ,[object Object],)  ,[object Object],
        
        ,[object Object],
        measurements = {

        }
        
        ,[object Object],
        ,[object Object], point, level ,[object Object], measurements.items():
            ,[object Object], ,[object Object], (-,[object Object], <= level <= ,[object Object],):  ,[object Object],
                test_result[,[object Object],] = ,[object Object],
                test_result[,[object Object],].append(,[object Object],)

Control System Integration

Integrate preset control into your room control system:

Crestron Integration

csharp

[object Object],
,[object Object], System;
,[object Object], Crestron.SimplSharp;

,[object Object], ,[object Object], ,[object Object],
{
    ,[object Object], ,[object Object], currentPreset = ,[object Object],;
    ,[object Object],;
    ,[object Object], PresetChangedHandler OnPresetChanged { ,[object Object],; ,[object Object],; }
    
    ,[object Object],
    {
        ,[object Object],
        {
            ,[object Object], (presetName.ToLower())
            {
                ,[object Object], ,[object Object],:
                    SendDspCommand(,[object Object],);
                    UpdateTouchPanel(,[object Object],);
                    ,[object Object],;
                    
                ,[object Object], ,[object Object],:
                    SendDspCommand(,[object Object],);
                    UpdateTouchPanel(,[object Object],);
                    ,[object Object],;
                    
                ,[object Object], ,[object Object],:
                    SendDspCommand(,[object Object],);
                    UpdateTouchPanel(,[object Object],);
                    ,[object Object],;
                    
                ,[object Object],:
                    CrestronConsole.PrintLine(,[object Object],);
                    ,[object Object],;
            }
            
            currentPreset = presetName;
            OnPresetChanged?.Invoke(,[object Object], SimplSharpString(presetName));
        }
        ,[object Object], (Exception e)
        {
            ErrorLog.Error(,[object Object],);
        }
    }
    
    ,[object Object],
    {
        ,[object Object],
        CrestronConsole.PrintLine(,[object Object],);
    }
}

Touch Panel Interface

Create an intuitive interface for preset selection:

javascript

[object Object],
,[object Object], ,[object Object], = {
    ,[object Object],: {
        ,[object Object],: { ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object], },
        ,[object Object],: { ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object], },
        ,[object Object],: { ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object], },
        ,[object Object],: { ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object], }
    },
    
    ,[object Object],(,[object Object],) {
        ,[object Object],
        ,[object Object],.,[object Object],(,[object Object],.,[object Object],).,[object Object],(,[object Object], {
            touchPanel.,[object Object],(config.,[object Object],, ,[object Object], {
                ,[object Object],.,[object Object],(preset);
            });
        });
    },
    
    ,[object Object],(,[object Object],) {
        ,[object Object],
        ,[object Object],.,[object Object],();
        ,[object Object],.,[object Object],(preset);
        
        ,[object Object],
        dspController.,[object Object],(preset);
        
        ,[object Object],
        ,[object Object],.,[object Object],(,[object Object],);
    },
    
    ,[object Object],(,[object Object],) {
        ,[object Object],.,[object Object],(,[object Object],.,[object Object],).,[object Object],(,[object Object], {
            touchPanel.,[object Object],(btn.,[object Object], + ,[object Object],, ,[object Object],); ,[object Object],
        });
    },
    
    ,[object Object],(,[object Object],) {
        ,[object Object], btnId = ,[object Object],.,[object Object],[preset].,[object Object],;
        touchPanel.,[object Object],(btnId + ,[object Object],, ,[object Object],);
    }
};

2. Version Control

Track preset changes over time:

python

[object Object],
,[object Object], ,[object Object],:
    ,[object Object], ,[object Object],(,[object Object],):
        ,[object Object],.preset_id = preset_id
        ,[object Object],.versions = []
        
    ,[object Object], ,[object Object],(,[object Object],):
        ,[object Object],
        version = {
            ,[object Object],: datetime.now().isoformat(),
            ,[object Object],: preset_data,
            ,[object Object],: comment,
            ,[object Object],: ,[object Object],(,[object Object],.versions) + ,[object Object],
        }
        
        ,[object Object],.versions.append(version)
        ,[object Object],._write_to_file()
        
    ,[object Object], ,[object Object],(,[object Object],):
        ,[object Object],
        ,[object Object], ,[object Object], < version_number <= ,[object Object],(,[object Object],.versions):
            ,[object Object], ,[object Object],.versions[version_number - ,[object Object],][,[object Object],]
        ,[object Object], ValueError(,[object Object],)

3. Performance Monitoring

Monitor preset performance over time:

javascript

[object Object],
,[object Object], ,[object Object], {
    ,[object Object],(,[object Object],) {
        ,[object Object],.,[object Object], = {};
        ,[object Object],.,[object Object], = {};
    }
    
    ,[object Object],(,[object Object],) {
        ,[object Object], (!,[object Object],.,[object Object],[presetId]) {
            ,[object Object],.,[object Object],[presetId] = {
                ,[object Object],: ,[object Object],,
                ,[object Object],: ,[object Object],,
                ,[object Object],: ,[object Object],
            };
        }
        
        ,[object Object],.,[object Object],[presetId].,[object Object],++;
        ,[object Object],.,[object Object],[presetId].,[object Object], += duration;
        ,[object Object],.,[object Object],[presetId].,[object Object], = 
            ,[object Object],.,[object Object],[presetId].,[object Object], / ,[object Object],.,[object Object],[presetId].,[object Object],;
    }
    
    ,[object Object],(,[object Object],) {
        ,[object Object], (!,[object Object],.,[object Object],[presetId]) {
            ,[object Object],.,[object Object],[presetId] = [];
        }
        
        ,[object Object],.,[object Object],[presetId].,[object Object],({
            ,[object Object],: ,[object Object], ,[object Object],(),
            ,[object Object],: rating,
            ,[object Object],: comment
        });
    }
    
    ,[object Object],(,[object Object],) {
        ,[object Object], {
            ,[object Object],: ,[object Object],.,[object Object],(),

            ,[object Object],: ,[object Object],.,[object Object],()
        };
    }
}

Audio Parameter Optimization

Optimizing audio parameters for different room sizes requires understanding acoustic principles:

Small Conference Room (6-8 people)

Parameter	Value	Reasoning
Mic Gain	42-45 dB	Close proximity to participants
AEC Reference	-20 dB	Moderate echo path
Speaker EQ	Flat	Minimal room correction needed
Compression	2:1	Light dynamics control

Medium Conference Room (12-16 people)

Parameter	Value	Reasoning
Mic Gain	45-48 dB	Increased distance coverage
AEC Reference	-18 dB	Longer echo paths
Speaker EQ	2-4 dB @ 200Hz cut	Room mode compensation
Compression	3:1	More dynamics control

Large Conference Room (20+ people)

Parameter	Value	Reasoning
Mic Gain	48-54 dB	Maximum coverage needed
AEC Reference	-15 dB	Complex echo patterns
Speaker EQ	Custom per measurement	Significant room correction
Compression	4:1	Strong dynamics control

Acoustic Treatment Considerations

,[object Object], ,[object Object],(,[object Object],):
    ,[object Object],
    
    ,[object Object],

    ,[object Object],
    ,[object Object], rt60 < ,[object Object],:  ,[object Object],

                    UpdateTouchPanel(,[object Object],);
                    ,[object Object],;
                    
                ,[object Object],:
                    CrestronConsole.PrintLine(,[object Object],);
                    ,[object Object],;
            }
            
            currentPreset = presetName;
            OnPresetChanged?.Invoke(,[object Object], SimplSharpString(presetName));
        }
        ,[object Object], (Exception e)
        {
            ErrorLog.Error(,[object Object],);
        }
    }
    
    ,[object Object],
    {
        ,[object Object],
        CrestronConsole.PrintLine(,[object Object],);
    }
}

Touch Panel Interface

Create an intuitive interface for preset selection:

javascript

[object Object],
,[object Object], ,[object Object], = {
    ,[object Object],: {
        ,[object Object],: { ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object], },
        ,[object Object],: { ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object], },
        ,[object Object],: { ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object], },
        ,[object Object],: { ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object],, ,[object Object],: ,[object Object], }
    },
    
    ,[object Object],(,[object Object],) {
        ,[object Object],
        ,[object Object],.,[object Object],(,[object Object],.,[object Object],).,[object Object],(,[object Object], {
            touchPanel.,[object Object],(config.,[object Object],, ,[object Object], {
                ,[object Object],.,[object Object],(preset);
            });
        });
    },
    
    ,[object Object],(,[object Object],) {
        ,[object Object],
        ,[object Object],.,[object Object],();
        ,[object Object],.,[object Object],(preset);
        
        ,[object Object],
        dspController.,[object Object],(preset);
        
        ,[object Object],
        ,[object Object],.,[object Object],(,[object Object],);
    },
    
    ,[object Object],(,[object Object],) {
        ,[object Object],.,[object Object],(,[object Object],.,[object Object],).,[object Object],(,[object Object], {
            touchPanel.,[object Object],(btn.,[object Object], + ,[object Object],, ,[object Object],); ,[object Object],
        });
    },
    
    ,[object Object],(,[object Object],) {
        ,[object Object], btnId = ,[object Object],.,[object Object],[preset].,[object Object],;
        touchPanel.,[object Object],(btnId + ,[object Object],, ,[object Object],);
    }
};

Best Practices

1. Document Your Presets

Create comprehensive documentation for each preset:

yaml

[object Object],
,[object Object], ,[object Object],
,[object Object], ,[object Object],
,[object Object], ,[object Object],
,[object Object], [,[object Object],, ,[object Object],]

,[object Object],
  ,[object Object],
    ,[object Object], ,[object Object], ,[object Object],
      ,[object Object], ,[object Object],
      ,[object Object], ,[object Object],
      ,[object Object], ,[object Object],
    ,[object Object], ,[object Object], ,[object Object],
      ,[object Object], ,[object Object],
      ,[object Object], ,[object Object],
      ,[object Object], ,[object Object],
      
  ,[object Object],
    ,[object Object], ,[object Object],
    ,[object Object], ,[object Object],
    ,[object Object], ,[object Object],
    
  ,[object Object],
    ,[object Object], ,[object Object],
    ,[object Object], ,[object Object],
    ,[object Object], ,[object Object],
    
,[object Object],
  ,[object Object], ,[object Object],
  ,[object Object], ,[object Object],
  ,[object Object], ,[object Object],

2. Version Control

Track preset changes over time:

python

[object Object],
,[object Object], ,[object Object],:
    ,[object Object], ,[object Object],(,[object Object],):
        ,[object Object],.preset_id = preset_id
        ,[object Object],.versions = []
        
    ,[object Object], ,[object Object],(,[object Object],):
        ,[object Object],
        version = {
            ,[object Object],: datetime.now().isoformat(),
            ,[object Object],: preset_data,
            ,[object Object],: comment,
            ,[object Object],: ,[object Object],(,[object Object],.versions) + ,[object Object],
        }
        
        ,[object Object],.versions.append(version)
        ,[object Object],._write_to_file()
        
    ,[object Object], ,[object Object],(,[object Object],):
        ,[object Object],
        ,[object Object], ,[object Object], < version_number <= ,[object Object],(,[object Object],.versions):
            ,[object Object], ,[object Object],.versions[version_number - ,[object Object],][,[object Object],]
        ,[object Object], ValueError(,[object Object],)

3. Performance Monitoring

Monitor preset performance over time:

javascript

[object Object],
,[object Object], ,[object Object], {
    ,[object Object],(,[object Object],) {
        ,[object Object],.,[object Object], = {};
        ,[object Object],.,[object Object], = {};
    }
    
    ,[object Object],(,[object Object],) {
        ,[object Object], (!,[object Object],.,[object Object],[presetId]) {
            ,[object Object],.,[object Object],[presetId] = {
                ,[object Object],: ,[object Object],,
                ,[object Object],: ,[object Object],,
                ,[object Object],: ,[object Object],
            };
        }
        
        ,[object Object],.,[object Object],[presetId].,[object Object],++;
        ,[object Object],.,[object Object],[presetId].,[object Object], += duration;
        ,[object Object],.,[object Object],[presetId].,[object Object], = 
            ,[object Object],.,[object Object],[presetId].,[object Object], / ,[object Object],.,[object Object],[presetId].,[object Object],;
    }
    
    ,[object Object],(,[object Object],) {
        ,[object Object], (!,[object Object],.,[object Object],[presetId]) {
            ,[object Object],.,[object Object],[presetId] = [];
        }
        
        ,[object Object],.,[object Object],[presetId].,[object Object],({
            ,[object Object],: ,[object Object], ,[object Object],(),
            ,[object Object],: rating,
            ,[object Object],: comment
        });
    }
    
    ,[object Object],(,[object Object],) {
        ,[object Object], {
            ,[object Object],: ,[object Object],.,[object Object],(),
            ,[object Object],: ,[object Object],.,[object Object],(),
            ,[object Object],: ,[object Object],.,[object Object],()
        };
    }
}
