May I request that the wave library support audio formats greater than 16 bit. I am hoping to use GNU Radio (http://www.gnu.org/software/gnuradio/) Python software with HPSDR (http://hpsdr.org/) hardware, but the HPSDR audio is 24 bit. The extra dynamic range is required for weak signal work. Many audio cards are now coming on the market with 24 bit capability. |

Currently 24-bit wave files are supported at least in 2.7, 3.3, and 3.4 (there are tests for this). The audioop module yet not supports 24-bit data, but this is another issue. |

Serhiy, you're welcome to set issues to pending, but please don't forget to close them after a certain time... |

Actually 24-bit samples are supported only on little-endian platforms (see issue19276). Here is simple patch which makes them supported on big-endian too. |

And supporting the feature only on some platforms (without good reasons) is a bug. |
