IEEE Float .wav files have almost identical structure to standard PCM .wav files. Currently, wave.py gives an unknown format error when attempting to read IEEE Float .wav files. This patch causes wave.py to read those files properly. No changes were made to wave_write, only wave_read. |

Logged In: YES user_id=99874 I don't know anything about the .wav format, but the patch is particularly inoffensive... it simply allows a second format constant in the WAVE header without raising an error. I recomend applying the patch as soon as someone else who DOES know the .wav format can confirm that it's being done right. |

Logged In: YES user_id=11375 Looking at the WAV format description at http://ccrma.stanford.edu/CCRMA/Courses/422/projects/WaveFormat , it looks like the patch isn't correct. There's an ExtraParams field after the header that's only present if the format is not PCM. If this is correct, the patch should also add code to read this field and either store it somewhere or just discard it. |

Since there was no follow-up to Andrew's remark that the patch is incorrect, I conclude that the submitter either lost interest in it, or agrees that the patch is indeed incorrect. Rejecting it as invalid. |

I am the original author ... just ran into the same exact issue 6 years later, and google turned up this ticket. This bug is still unfixed, and the patch is still correct. The patch does not reject any valid WAV files. Its worst sin is accepting and processing (correctly) some technically invalid files, which I would argue is actually desirable behavior. |
