mp3

问题 I am decoding audio using MediaExtractor , MediaCodec , and AudioTrack . I am configuring the AudioTrack using the MediaFormat returned by MediaCodec.getOutputFormat() after receiving MediaCodec.INFO_OUTPUT_FORMAT_CHANGED from the MediaCodec .

问题 I am trying to find a way to create text to speech in python (I am on windows 7). I am using pyinstaller to compile this program.

Also try the different Endian settings; -L; -B; -x though only use one at a time,

问题 I need to convert the recorded audio file which is in 3gp format to mp3 format. Any suggestions pls. 回答1: Rather messy, but you could try this: Use isobox4j (see https://contributions.coremedia.com/isobox4j/wiki/IsoParser) to read the AMR audio out of the 3gp file. Use one of the options listed in How to encode a WAV to a mp3 on a Android device to encode it. Never used isobox4j: started working with it but moved on to a different project before I was done but it looks like it will give you
