Spatial Mapping
Frequency-dependent coverage heatmaps showing how sound distributes across your measurement positions
What is Spatial Mapping?
Spatial Mapping visualizes how sound coverage varies across your measurement area. By interpolating between measurement positions, AudioMap generates heatmaps that reveal level variations, frequency-dependent coverage patterns, and potential problem areas.
The heatmap uses your room geometry and measurement positions to create a continuous coverage map — making it easy to see where sound is too loud, too quiet, or spectrally uneven.
What You See
Coverage Heatmap
Color-coded map overlaid on your room geometry. Hot colors indicate higher levels, cool colors indicate lower levels at the selected frequency.
Measurement Positions
Individual measurement points marked on the map with their measured values. These are the data points from which the heatmap is interpolated.
Speaker Positions
Source locations shown on the map for spatial reference. Helps correlate coverage patterns with speaker placement.
Generating a Heatmap
Define Room
Set up room geometry in the Measurement Wizard with walls, dimensions, and speaker positions.
Take Measurements
Capture measurements at multiple positions across the coverage area. More positions = finer heatmap.
Select Frequency
Choose the frequency or frequency range to visualize. The heatmap updates to show coverage at that frequency.
View Coverage
The heatmap interpolates between measurement points to create a continuous coverage visualization.
Frequency Selection
Coverage patterns change dramatically with frequency. Low frequencies tend to be more uniform (longer wavelengths), while high frequencies show more variation due to directivity and interference effects.
Sub-bass (20-80 Hz)
Room modes dominate. Look for nulls and peaks from standing waves.
Bass (80-250 Hz)
Transition zone. Some modal behavior, beginning of directional effects.
Midrange (250-4000 Hz)
Primary speech/music range. Most critical for even coverage.
High (4000-20000 Hz)
Highly directional. Strong off-axis roll-off from most speakers.
Interpreting Results
Even Coverage
Uniform colors across the map indicate consistent level. Aim for less than 6 dB variation across the seating area.
Hot Spots
Concentrated high-level areas may indicate speaker overlap, reflections, or positions too close to a source.
Dead Zones
Cold spots may indicate coverage gaps, destructive interference, or positions outside a speaker's coverage pattern.
View Modes
2D Plan View
Top-down view of the room with the heatmap overlaid. Best for evaluating horizontal coverage uniformity and identifying coverage gaps in the seating area.

3D Perspective View
Three-dimensional view showing the room geometry with coverage data mapped onto surfaces. Provides spatial context for understanding how coverage relates to the room structure.
