Accuracy and scope

Supports little-endian RIFF WAV: PCM 8/16/24/32-bit or float32 input, 1–8 channels. Compressed, RF64 and WAVE_FORMAT_EXTENSIBLE input are rejected. Maximum 40 MB total and 12 million samples. Output is integer PCM; values outside full scale are clipped. Metadata is not retained. No resampling or dithering. Peak normalization is not LUFS normalization. Joining requires matching sample rate and channel count.

This tool runs locally in your browser. Input and output are not sent to a processing server. Copy or download your result before leaving the page.

Exports reject samples above full scale unless you explicitly allow hard clipping. The output summary reports the affected sample count. Clipping can introduce distortion; lower the level or peak-normalize first.

Finish the processed selection with leading/trailing silence, up to ten repeats and gaps. Stereo balance attenuates one channel and requires two output channels. Polarity inversion changes signal sign. Repeats include the applied fades. Output is capped at 12 million samples.
