Files up to 16 MiB, mono or stereo at 32, 44.1 or 48 kHz, up to 60 seconds and 24 MiB of PCM; the 20-second deadline includes reading and native decoding. DSP exports 16-bit WAV, drops source metadata and warns before clipping. The original bytes stay available. MP3 ID3 edits: up to 120 seconds, ID3v2.3 or 2.4, tags up to 2 MiB, PNG or JPEG cover up to 1 MiB and 4 MP; the audio frames are unchanged. Unsupported, encrypted or signed data is rejected. Supported formats: WAV (PCM 16, 24 or 32 bit, or float32 with |x| up to 16), MP3 (MPEG-III, ID3v2.3 or 2.4) and M4A (AAC-LC).

How can I check this result?
Compare the peak and RMS before and after, and look for clipped samples. Reopen the WAV to check its duration and channels, and keep the original file, which still has its metadata.
