B4J Question Record voice with jaudiorecord

[le_toubib]

Hi I'm trying to record simple voice using jaudiorecord library and then upload the wav file to a server... But the output is a very large file even if I use mono with a bit rate of 5525 . Its still too large for uploading.
What's the best way to get very small file size that can be playable programmatically.. With a reasonable audio quality for simple audio note?

You probably need to compress the file to Mp3 or Ogg format before uploading it. I don't remember seeing a Library for B4j that can do it. You may be able to find a stand alone app that you can call via the shell to do the compression.
