How to use this tool
Upload the source audio, choose its target format and bitrate, then listen for the intended start, end, and loudness.
Results and examples
Play the complete output to check dropouts, duration, and missing tags before treating it as a distribution copy.
Worked example
When converting a spoken MP3 announcement to WAV, compare its duration and channels rather than expecting a 192 kbps WAV file.
Limitations
- WAV output uses 16-bit PCM and ignores the compressed-audio bitrate setting.
- Re-encoding MP3 or OGG cannot recover frequencies or detail already absent from the source.

Frequently asked questions
Why is WAV larger?
PCM does not use MP3-style lossy compression, so duration and channels strongly affect its size.
Does 320 kbps restore quality?
It changes the new encoding budget, not the information remaining in an already compressed recording.
