Among all these formats MATLAB is mostly used. Parameters filename string or open file handle. [-1 -2]? os.path.exists(my_file) 可以使用scipy.io.wavfile.read(somefile)来读取.wav音频文件。 它会返回一个元组，第一项为音频的采样率，第二项为音频数据的numpy数组。 用法： from scipy.io import wavfile Notes. Apparently when the output of ffmpeg is sent to stdout, the program does not fill in the RIFF chunk size of the file header. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under Featured on Meta That is supposed to be the size of the RIFF "chunk". I was expecting to get a (Nx1) dimensional array with the total number of samples.I have looked online and didn't find anything, and even after converting the audio signal to mono, I still get a Nx2 array so I don't think these are the left and right channel (but I could be wrong).The last dimension is the number of channels. while line: Arff. Parameters filename [string or open file handle] Input wav file. Another modern and convenient solution is to use pysoundfile, which can read and write a wide range of audio file formats: import numpy as np import soundfile as sf data = np.random.uniform(-1, 1, 44100) sf.write('new_file.wav', data, 44100) your coworkers to find and share information.

方法二使用os.path.isfile检查路径是否为文件，如果文件存在返回True。import os.path You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.

Input and output (scipy.io) index; modules; next; previous; scipy.io.wavfile.read¶ scipy.io.wavfile.read(filename, mmap=False) [source] ¶ Return the sample rate (in samples/sec) and data from a WAV file. Stack Overflow for Teams is a private, secure spot for you and My problem is that the output array is (Nx2) dimensional and I don't know what the two dimensions represents. Writes a simple uncompressed WAV file. I'm currently learning to work with audio and i don't understand the scipy.io.wavfile.read() function. 3.

Learn how to use python api scipy.io.wavfile.read 5. with fileinput.FileInput(fileToSearch, inplace=True, backup='.bak') as file: This works perfectly on both Windows 10 (FFmpeg 3.3.6) and Ubuntu 17.10 (FFmpeg 3.3.4-2). Note that the second four bytes, interpreted as a four byte hex number, are 0xFFFFFFFF. However, it needs to save a converted file to disk.And here is the code I try to get the FFmpeg output from stdout and load it into scipy wavfile.A work-around for your code is to patch the RIFF chunk size manually before the data is passed to Thanks for contributing an answer to Stack Overflow! See also. 2 means that you have a stereo wav file as input. A 1-D or 2-D NumPy array of either integer or float data-type. Data-type is determined from the file; Stack Overflow works best with JavaScript enabled So far so good.My problem is that the output array is (Nx2) dimensional and I don't know what the two dimensions represents. The following are 40 code examples for showing how to use scipy.io.wavfile.read().These examples are extracted from open source projects.

I tried using the scipy.io.wavfile.read function the get the soundpressure of a soundtrack and get, as indicated in the doc two outputs : the sampling rate and a data numpy array.
