Audio stays on this device. No upload or microphone recording. Reverse each channel's PCM order independently; unchanged sample rate/channels/frame count. WAV quantizes to16bits; source metadata is not copied. 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).
