    How to use Reviewed Audio Silence Remover

    1. Choose the WAV and run Find quiet regions for review.
    2. Inspect the proposed IDs with the quiet threshold, minimum span and retained padding in mind.
    3. Enter only the IDs to remove, confirm the review and select Render only my approved cuts.
    4. Audition the joins before saving the rendered WAV.

    Example: Reviewed Audio Silence Remover

    Inspect silence without immediately deleting it.

    You add
    One-second mono WAV containing only zero samples. Mode: Find quiet regions for review; threshold: -45 dBFS; minimum quiet span: 0.3 seconds; padding: 0.05 seconds.
    You get
    The proposed cut list contains a quiet region with retained end padding. Review mode downloads the candidate CSV without making an audio cut; its threshold and padding remain entered form settings.

    Options

    Quiet RMS threshold
    A higher, less negative threshold identifies more low-level material as quiet. Review the candidate list after changing it.
    Minimum quiet span and padding
    Minimum span ignores shorter pauses. Padding keeps material at both ends of each proposed cut and can make a short candidate too small to remove.

    Supported inputs and limits

    Supported duration600 seconds
    RIFF WAV only: mono/stereo PCM16, PCM24, PCM32 or float32 at 8–96 kHz; up to 128 MiB and 600 seconds. Compressed WAV, extended headers and other containers are refused. Work stays on your device. Quietness is detected from short RMS windows, not speech recognition. Render mode requires explicit review; an empty ID list retains all regions. Detection uses non-overlapping 10 ms RMS windows.

    Quiet does not always mean expendable

    Breathing, room sound and pauses can fall below an RMS threshold. Raise or lower the threshold and rerun the review instead of assuming every candidate is unwanted. Padding retains some material beside the detected quiet span, but it cannot guarantee a natural join.

    Approve the list for the current settings

    IDs refer to the candidates calculated for the selected recording and settings. A changed threshold or file can produce a different list. Keep the source, review the new list and listen across each join; this tool does not add a crossfade or understand sentence boundaries.
