Solution 1: Convert online. You can use online-convert service. It has it's own API and it supports conversion directly from URL, so you don't even need to read the file into memory. Solution 2: Convert locally with temp file This repo is prepared for audio file conversation from .mp3, .mp4, etc to .wav format, for win machine. If you use Linux need to take care of the folder/file separator (‘\’, ‘/’ ) inside code.

Bases: moviepy.Clip.Clip. Base class for audio clips. See AudioFileClip and CompositeSoundClip for usable classes. An AudioClip is a Clip with a make_frame attribute of the form `` t -> [ f_t ]`` for mono sound and t-> [ f1_t, f2_t ] for stereo sound (the arrays are Numpy arrays). The f_t are floats between -1 and 1.

In my previous notebook, we tried to convert mp3 audio files to wav files. But it took almost 25 minutes to convert the Validation files. In this notebook we'll try a different way to convert the mp3 files to wav files using joblib. This notebook takes only 8-9 minutes to process the validation files. (3times faster) Reference : Idea is from 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
Start of by creating an audio file with some speech. This can be any audio file with English words. Save the file as transcript.mp3. If you are unsure where to get an spoken words audio file, you can use Bluemix to generate one. Install prequisites. To run the app you need several things installed: Python 3; the module pydub; the program ffmpeg
Third Step: Make a folder. Make a new folder at the directory of your choice. Put video (.mp4 file) and create a python script in that folder. In my case: Desktop>mp42txt (Folder, containing py

Sample rate of WAV file. data numpy array. Data read from WAV file. Data-type is determined from the file; see Notes. Data is 1-D for 1-channel WAV, or 2-D of shape (Nsamples, Nchannels) otherwise. If a file-like input without a C-like file descriptor (e.g., io.BytesIO) is passed, this will not be writeable. Notes. Common data types:

Set all the parameter of the wav file as you have shared w.r.t the audacity Wave_write.setparams(tuple) The tuple should be (nchannels, sampwidth, framerate, nframes, comptype, compname), with values valid for the set*() methods.
