🎫 Convert Wav To Mp3 Python

Python Program from pydub import AudioSegment # Convert wav to mp3 audio = AudioSegment.from_wav("input.wav") audio.export("output.mp3", format="mp3") print('Success. Given audio converted to mp3.') Output Success. Given audio converted to mp3. A new audio file output.mp3 should be created. Summary

^{2 Answers. In general, you would simply load the audio into an array of shape (n, k), where n is number of channels and k number of loaded samples. By averaging along channel axis (sum and divide by number of channels), you'd get your mono signal. As @CodeSurgeon pointed out, do mixer.init (channels=1) -> docs. Use mixer.set_num_channels property.} ^{If you do get to the real silk data, you can decode it with the original Skype Silk SDK. There is probably no python port for this, but you can invoke external libs from python. Once decoded, use ffmpeg/Audacity raw import/other to convert to WAV/mp3 and test the audio. Then in python, using the wave library or wavio api should work.} ^{1 Answer. 1 year late but try using a buffer to keep the audio bytes in memory. from pydub import AudioSegment import speech_recognition as sr import io r = sr.Recognizer () for i in range (5): audio = AudioSegment.from_wav ("some_wav.wav") audio_chunk = audio [int (i*1000):int (i*3000)] buffer = io.BytesIO () audio_chunk.export (buffer, format}

I am trying to seperate a section of audio from the video and save it as a wav file that can be used with other Python modules. I want to do this with MoviePy. I send parameters to the write_audiofile function, specifying the filename, fps, nbyte, and codec.

However, after obtained a numpy array using wav *= 32767 / max(0.01, np.max(np.abs(wav))), I want to convert it to a .mp3 file so that it will be easier to send it back as streaming response. Right now, I can convert .wav bytes object to a .mp3 file, but the problem is that I don't know how to convert the numpy array to a .wav bytes object.

1. I would forget about mp3 your compression technique replaces mp3 instead I would focus on raw audio in PCM format here. their process. PCM -> conversion to mp3 -> mp3 file -> decoding to PCM -> PCM. your process. PCM -> your compression trick -> SpentDeath file -> decoding to PCM -> PCM. just use same raw audio PCM as input into both

The following code can be used to play a WAV file, and wait for the file to finish playing before terminating the script: Python. import simpleaudio as sa filename = 'myfile.wav' wave_obj = sa.WaveObject.from_wave_file(filename) play_obj = wave_obj.play() play_obj.wait_done() # Wait until sound has finished playing.
