![]() Print("Exporting chunk.wav"\r\n'.Well, you might have many reasons to explain why you need to split a MP3 file into several parts, but the facts have proved that it is hard to achieve the goal. # Export the audio chunk with new bitrate. Normalized_chunk = match_target_amplitude(audio_chunk, -20.0) # Add the padding chunk to beginning and end of the entire chunk.Īudio_chunk = silence_chunk + chunk + silence_chunk Silence_chunk = AudioSegment.silent(duration=500) # Create a silence chunk that's 0.5 seconds (or 500 ms) long for padding. # Process each chunk with your parameters # (You may want to adjust this parameter.) # Consider a chunk silent if it's quieter than -16 dBFS. # Specify that a silent chunk must be at least 2 seconds or 2000 ms long. # Split track where the silence is 2 seconds or more and get chunks using # Define a function to normalize a chunk to a target amplitude.ĭef match_target_amplitude(aChunk, target_dBFS):Ĭhange_in_dBFS = target_dBFS - aChunk.dBFS # split_on_silence function for separating out silent chunks.įrom pydub.silence import split_on_silence ![]() Snippet # Import the AudioSegment class for processing audio and the Overall, I was able to split mp3 files, although I had to try different values for silence_threshold. Some of the parameters such as silence_threshold and target_dBFS may need some tuning to match your requirements. Here is a snippet that does what you asked. You may need to install ffmpeg/avlib if needed. You can install pydub with pip install pydub I found pydub to be easiest tool to do this kind of audio manipulation in simple ways and with compact code.
