Using mp3, mp4, m4a, mu-law, a-law or other lossy codecs during recording or transmission may reduce accuracy. If your audio is already in an encoding not supported by the API, transcode it to lossless FLAC or LINEAR16. If your application must use a lossy codec to conserve bandwidth, we recommend the AMR_WB, OGG_OPUS or SPEEX_WITH_HEADER_BYTE A shell sugars midi2audio and midiplay are provided instead of more verbose python -m midi2audio. # play MIDI $ midiplay input.mid # synthesize MIDI to audio $ midi2audio input.mid output.wav # also to FLAC $ midi2audio input.mid output.flac # custom sound font $ midi2audio -s sound_font.sf2 input.mid output.flac # custom sample rate TL;DR: Use subprocess and ffmpeg to convert the file to wav data, and pipe that data into np.frombuffer. The problem is, the subprocess still has to finish before frombuffer is used. unless it's possible to have the pipe written to on 1 thread while np reads it from another thread, which I haven't tested yet. The problem is that the downloaded audio file is either a .webm or a .mp4 file, which I'd like to convert to a .mp3 file. Is there a way to read the filetype (webm/mp4) first and then run a code that converts it to a mp3 file? I'd like to run it as a script in pycharm. Not as a command in the console. Thanks for your answers. Das Typ The first one, convert_to_wav(filename) takes a file path and uses PyDub to convert it from a non-wav format to .wav format. Once it's built, we'll use the function to convert Acme's first call, call_1.mp3, from .mp3 format to .wav. PyDub's AudioSegment class has already been imported. Remember, to work with non-wav files, you'll need ffmpeg. The output I showed was to let people know that I'm able to output to .wav. The closest I got to output espeak link to mp3 format is: espeak -f myfile --stdout | ffmpeg -i - -ar 44100 -ac 2 -ab 192k -f mp3 final.mp3 When I tried it I got many errors. The main task is that I want to be able to output mp3 file from espeak on Ubuntu.
