I am getting this error when trying to open a RIFF file (which as I understand it is a type of WAV) in python.
Failed to open file file.wav as a WAV due to: file does not start with RIFF id
When I inspect it with various tools which leads me to believe that it is really a WAV / RIFF file.
$ file file.wav
file.wav: MBWF/RF64 audio, stereo 96000 Hz
$ file -i file.wav
file.wav: audio/x-wav; charset=binary

January 2019. The Resource Interchange File Format (RIFF) is a generic file container format for storing data in tagged chunks. It is primarily used to store multimedia such as sound and video, though it may also be used to store any arbitrary data.
How to open a WAV file. Since WAV is quite a popular format, almost all devices today support it using built-in media players. On Windows, the Windows Media Player is capable of playing WAV files. On MacOS, iTunes or QuickTime can play WAV files.
Similar to the AVI and ASF format, WAV is only a file container. Audio content that is compressed with a wide variety of codecs and that is stored in a . wav file can be played back in Windows Media Player if the appropriate codecs are installed on the computer. The most common audio codecs that are used in .
This function opens a file to read/write audio data. The function needs two parameters - first the file name and second the mode. The mode can be 'wb' for writing audio data or 'rb' for reading. A mode of 'rb' returns a Wave_read object, while a mode of 'wb' returns a Wave_write object.
What you have is a 64-bit RIFF. wave does not support 64-bit RIFF files.

If your audio is okay, and you are able to read the file with librosa or scipy.io, we can simply read the file, write it back to a temporary wav file and then read it with the wave package again.
Example. Below, we get the RIFF id error.
>>> import wave
>>> wave.open('./SA1.WAV')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/pytorch/anaconda3/lib/python3.6/wave.py", line 499, in open
return Wave_read(f)
File "/home/pytorch/anaconda3/lib/python3.6/wave.py", line 163, in __init__
self.initfp(f)
File "/home/pytorch/anaconda3/lib/python3.6/wave.py", line 130, in initfp
raise Error('file does not start with RIFF id')
wave.Error: file does not start with RIFF id
We read into numpy with librosa, write back with soundfile.
import librosa
import soundfile as sf
>>> x,_ = librosa.load('./SA1.WAV', sr=16000)
>>> sf.write('tmp.wav', x, 16000)
>>> wave.open('tmp.wav','r')
<wave.Wave_read object at 0x7fbcb4c8cf28>
Similar to @kakrafoon 's answer but using soundfile to both read and write (in case you care about limiting the number of external dependencies):
import soundfile
import wave
file_path = "your_file.wav"
# Read and rewrite the file with soundfile
data, samplerate = soundfile.read(file_path)
soundfile.write(file_path, data, samplerate)
# Now try to open the file with wave
with wave.open(file_path) as file:
print('File opened!')
