New submission from Serhiy Storchaka: The audio modules often need convert between little endian and big endian data. The array module can be used to byteswap 16- and 32-bit samples, but it can't help with 24-bit samples. Python implemented function for swapping bytes is not very efficient. In any case the use of array is not so simple (see issue19276, issue19633).
The proposed patch adds efficient byteswap() function in the audioop module. byteswap(fragment, width) byteswaps every "width"-byte sample in the fragment and returns modified data. ---------- components: Library (Lib) files: audioop_byteswap.patch keywords: patch messages: 203273 nosy: serhiy.storchaka priority: normal severity: normal stage: patch review status: open title: Add audioop.byteswap() type: enhancement versions: Python 3.4 Added file: http://bugs.python.org/file32686/audioop_byteswap.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19641> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
