Use the subprocess Module to Convert MP3 to WAV in Python Conclusion In the realm of audio processing, converting audio files from one format to another is a common practice. It’s particularly prevalent to convert MP3 files to WAV, given the distinct characteristics and use cases of these two formats. this is how i got audio in byte strings format, recorded in python using 'speech_recognition` package: import speech_recognition as sr recognizer = sr.Recognizer() with mic as source: recognizer.adjust_for_ambient_noise(source) captured_audio = recognizer.record(source=mic, duration=30) audio_file = captured_audio.get_wav_data(convert_rate=44100) Set-up Python virtual environment, Jupyter notebook and convert files to .wav format Set-up speech recognition software (Google Cloud Speech-to-Text in my case) and transcribe (or recognise) audio Read audio and music meta data and duration of MP3, OGG, OPUS, MP4, M4A, FLAC, WMA, Wave and AIFF files with python 2 or 3 a Python CLI program for converting The output MP3 file should work on most new audio players. 3. Open a text editor (Nano or Vim on Linux/Unix/MacOS or Notepad on Windows) , type your story and save the file under “story.txt” name. 4. Type python polly.py in the console to convert your story file into an audio file. I am using MediaRecorder in ReactJS to record audio from the microphone and storing into the blob with MIME type "audio/mp3". I want to convert this blob to MP3 and upload it in S3 bucket. I am able to convert it into WAV by using audioContext, decodeAudioData and audioBufferToWav functions, but the size of the WAV is very large. Yes. ffmpeg/avlib version: 3.4. It's easier to debug since you can log the actual ffmpeg calls and manually run them in a shell, and also search google for info about the ffmpeg flags, etc. It's easier to verify that you have the ffmpeg binary installed and test that it works than a dll/dylib/so. Wave_write.writeframes(data) Write audio frames and make sure nframes is correct. once done close the file handle. Wave_write.close() Make sure nframes is correct, and close the file if it was opened by wave. This method is called upon object collection. I hope you can implement the python code based on these description. 4yO6ZF.
