I have also read Trying to convert an mp3 file to a Numpy Array, and ffmpeg just hangs, etc., and tried the main answers, but there was no simple solution. After spending hours on this, I'm posting it here with "Answer your own question – share your knowledge, Q&A-style". import numpy as np from scipy.io.wavfile import write rate = 44100 data = np.random.uniform (-1, 1, rate) # 1 second worth of random samples between -1 and 1 scaled = np.int16 (data / np.max (np.abs (data)) * 32767) write ('test.wav', rate, scaled) If you want Python to actually play audio, then this page provides an overview of some of the A Python script that converts audio files from the .m4a format to either .mp3 or .wav format using the pydub library. - GitHub - silkyland/simpleconv: A Python script that converts audio files from the .m4a format to either .mp3 or .wav format using the pydub library. With Scipy (to wav file) You can easily convert to wav and then separately convert wav to mp3. More details here. from scipy.io.wavfile import write samplerate = 44100; fs = 100 t = np.linspace (0., 1., samplerate) amplitude = np.iinfo (np.int16).max data = amplitude * np.sin (2. * np.pi * fs * t) write ("example.wav", samplerate, data.astype librosa.output.write_wav¶ librosa.output.write_wav (path, y, sr, norm=False) [source] ¶ Output a time series as a .wav file. Note: only mono or stereo, floating-point data is supported. For more advanced and flexible output options, refer to soundfile. Python で subprocess モジュールを使用して MP3 を WAV に変換する. subprocess モジュールは、さまざまなアプリケーションを実行するための新しいプロセスを作成します。. このモジュールの call () 関数を使用して、必要な変換を実行できます。. この関数からの出力 LtGj2O. How to restore the binary data into the audio file? but if i get the binary data of the audio file, i use the following way, def get_file_content (filePath): with open (filePath, 'rb') as fp: return fp.read () audio = AudioSegment (data=get_file_content (file_path), sample_width=2, frame_rate=22050, channels=1) However when i try to use the Modified 1 year, 3 months ago. Viewed 3k times. 2. I'm using ffmpeg-python. I would like to change the sample rate of the audio file. In ffmpeg-, it seems that you can change the sample rate as follows. ffmpeg -i" movie.mp3 "-y" movie.flac "-ar 44100. -ar is sample rate. I need to convert MP3 audio to WAV audio. I've done a fair amount of research and it looks like LAME can do the job for me. The converted WAV audio needs to be 16-bit mono at 11025Hz. I'd also preferably like to lower the volume by ~20dB. Can this be done with LAMe on the command line? In this article, we will explore different methods to convert MP3 to WAV in Python, catering to intermediate Python developers familiar with basic audio formats. We will delve into practical examples using libraries like pydub, ffmpeg, and the subprocess module. 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 Speech to text support wav files with LINEAR16 or MULAW encoded audio. Below is the code to get the frame rate and channel with code. def frame_rate_channel(audio_file_name): with wave.open(audio_file_name, "rb") as wave_file: frame_rate = wave_file.getframerate() channels = wave_file.getnchannels() return frame_rate,channels
