Why not convert vox audio files to MP3 format

[yangshc]

(https://github.com/a-schild/jave2#converting-any-audio-to-mp3)Examples Examples is "Converting any audio to mp3", but cannot parse audio files that convert vox suffixes. Why can't I convert audio files with the vox suffix to MP3?

Do you have a sample file and some sample code? Can you do the conversion with ffmepg?

Ffmepg use ====>>>>

PS C:\jave>.\ffmpeg-amd64-3.2.0.exe -i .\source.vox -hide_banner ---->> .\source.vox: Invalid data found when processing input

PS C:\jave>.\ffmpeg-amd64-3.2.0.exe -f vox -i .\source.vox -vn -acodec libmp3lame -ab 128000 -ac 1 -ar 44100 -vol 256 -f mp3 -y .\target.mp3 -hide_banner ---->> Unknown input format: 'vox'

the last word: But the vox audio file, in fact, is normal. Can you give me some help? Thank you

Do you have a sample file and some sample code? Can you do the conversion with ffmepg?

I don't know how to give you a sample file

[a-schild]

It looks like the VOX audio file is raw audio data, with no header describing the audio streams/layout. ffmepg can't convert this on it's own, without additional informations about the source.

You have to look at the ffmpeg project, how to do this with vanilla ffmpeg. Once you have the correct ffmpegs flags I can look on how to incorporate it in jave
