Which WAV recordings can I convert?
Use a WAV containing signed 16-bit PCM samples with one mono or stereo audio track at 8–48 kHz. Floating-point, higher-bit-depth, compressed and multichannel WAV files are not supported. Inspection checks the actual file; current file and duration limits appear above.
What changes when I save WAV as MP3?
MP3 is a new lossy encoding at 128 kbit/s, so it does not preserve every original PCM sample. Embedded tags and chapters are omitted. Review and confirm each required choice before converting; identical sound or a smaller file is not guaranteed.
Should I keep the original WAV?
Keep the original WAV if you need its uncompressed samples for editing or later encoding. This task creates a listening or sharing copy and cannot recover detail already missing from the recording.
