librosa

问题 For my project I have to detect if two audio files are similar and when the first audio file is contained in the second. My problem is that I tried to use librosa the numpy.correlate. I don't know if I'm doing it in the right way. How can I detect if audio is contained in another audio file? import librosa import numpy long_audio_series, long_audio_rate = librosa.load("C:\\Users\\Jerry\\Desktop\\long_file.mp3") short_audio_series, short_audio_rate = librosa.load("C:\\Users\\Jerry\\Desktop\

问题 I am trying to sample (convert analog to digital) mp3 files via the following Python code using the librosa library, but it takes too much time (around 4 seconds for one file). I suspect this is because librosa doesn't support mp3 and hence uses the slower audioread to sample mp3 Code: import time import librosa s = time.time() for i in mp3_list[:10]: # list of mp3 file paths, doing for 10 files y, sr = librosa.load(i) print('time taken =', time.time() - s) time taken = 36.55561399459839 I

问题 The situation I am using VAD (Voice Activity Detection) from WebRTC by using WebRTC-VAD, a Python adapter. The example implementation from the GitHub repo uses Python's wave module to read PCM data from files. Note that according to the comments the module only works with mono audio and a sampling rate of either 8000, 16000 or 32000 Hz. What I want to do Read audio data from arbitrary audio files (MP3 and WAV files) with different sampling rates, convert them into the PCM-representation that

问题 I'm reading a file in Python using either of librosa, wave or soundfile libraries and I need to push the chunk (any size) to a HTTP stream. By specification, stream string input requires me to convert frames into RAW s16le format. I tried multiple options including: soundarray,rate = librosa.load(pathToWavFile, dtype="<i2") str = b''.join(soundarray) But this just creates an empty audio stream. What am I doing wrong? 回答1: You can try pydub to convert audio to audio-segment, split audio

问题 I am trying to load an audio file in python and process it with google speech recognition The problem is that unlike in C++, python doesn't show data types, classes, or give you access to memory to convert between one data type and another by creating a new object and repacking data I dont understand how it's possible to convert from one data type to another in python The code in question is below, import speech_recognition as spr import librosa audio, sr = librosa.load('sample_data/metal.mp3

问题 I have recently tried to install librosa on Windows using pip install librosa . Nevertheless, this error appears: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall. As a solution, I have executed conda update --all , and conda install numba=0.39.0 , without any improvement. Thank you in advanced. 回答1: You just have to type the command you want to execute with the --user
