WAVMP3
This route decodes a supported WAV source and makes a new MP3 from its first audio stream with LAME VBR quality setting 2.
How it works
Queue WAV files, then download new MP3 audio.
Run the fixed conversion
Start the queue to process one file at a time with this route’s LAME VBR quality 2 FFmpeg profile.
Check and download each MP3
Review a completed result in compatible software, then download its separately named MP3 file.
Processing boundaries
Fixed LAME VBR quality 2 output from the first audio stream.
The profile maps only the first audio stream, omits video, removes metadata and chapters, and uses libmp3lame at quality setting 2.
Convert WAV to MP3WAV files up to 100 MB
Only non-empty .wav uploads of 100 MB or less are accepted. Unsupported or unreadable audio sources cannot be converted.
New LAME VBR quality 2 encoding
The downloaded MP3 is lossy and newly encoded. It does not copy the WAV audio stream or guarantee a particular bitrate or size.
First audio stream only
Only the first audio stream is mapped. Video, alternate tracks, subtitles, and attachments are excluded from this audio-only result.
No source tags or editing controls
Source metadata and chapters are removed. This route provides no trim, stream-selection, bitrate, sample-rate, channel, or quality controls.
WAV-to-MP3 details
Understand the file before you convert
Which WAV files can I upload?+−
Use non-empty .wav files up to 100 MB. Host FFmpeg must be able to read an audio stream in the source.
What does the downloaded MP3 contain?+−
A successful conversion contains a newly encoded, audio-only MP3 result from only the first audio stream using LAME VBR quality 2.
Can I add more than one file?+−
Yes. Add multiple eligible files. The browser submits each queue item sequentially and every completed result has a separate download.
Is WAV to MP3 a stream copy?+−
The downloaded MP3 is lossy and newly encoded. It does not copy the WAV audio stream or guarantee a particular bitrate or size.
Will source metadata or chapters remain?+−
No. The conversion profile removes source metadata and chapters. Alternate audio tracks, video, subtitles, and attachments are not included.
Can I change MP3 settings or trim the audio?+−
No. There are no trimming, stream-selection, bitrate, sample-rate, channel, or quality controls.
Does the preview guarantee the conversion will succeed?+−
No. Browser playback support and host FFmpeg readability are different checks. A file must be readable by FFmpeg for conversion, and playback depends on browser support.
