Frequency Band Modes

1-Band

Shows overall volume over time, no frequency separation.

3-Band

Separates audio into low, mid, and high frequencies.

10-Band (Recommended)

Splits audio into 10 logarithmically spaced frequency bands, highlighting frequency-specific energy over time.

25-Band

Provides fine-grained frequency separation across 25 bands, revealing detailed spectral variations throughout the track.

Max Audio Length Limits

To ensure stability and performance, avoid exceeding these limits before your visuals may become inconsistent.

How Images Are Generated

  1. 1

    Audio Normalization

    Converts to WAV and balances volume.

  2. 2

    Frequency Splitting

    Separates audio into frequency bands (low to high).

  3. 3

    Waveform Rendering

    Each band becomes a waveform image.

  4. 4

    Pixel Conversion

    Waveforms are resized into thin strips where brightness equals volume (white = loud, black = quiet).

  5. 5

    Stacking & Combining

    Bands are combined into one spectrogram image (e.g., 8000x10 or 8000x25).

  6. 6

    Cleanup

    Temporary files are removed, leaving only your final image.
