[flac-dev] FLAC-compress data with Python

2014-03-15 Thread Nouvelle Collection
Hello, I would like to compress some data, stored in a Numpy Array (Python) with something like (*): flac.compress(my_array) without having to put data in a .wav file, without having to deal with containers, etc., i.e. : *raw data in / raw data out* Do you have an idea on how to do that with FL

[flac-dev] More than 150 MB / second encoding ?

2014-03-16 Thread Nouvelle Collection
Hello, Is there some version of FLAC that allows very very fast encoding (i.e. able to process at least 150 MB / second of .wav input data on a standard computer : laptop computer, Core i5/i7, Windows 7 64 bit, 8 GB RAM) ? (It's ok to have a compression ratio which is a little bit lower than trad

Hello FLAC-dev, Do you know if there is some good educational documentation showing FLAC's internal design in a few steps, like this doc for monkeysaudio : http://www.monkeysaudio.com/theory.html If not, what is the principle of the algorithm in a few big steps (example : 1. Conversion to mid/s

[flac-dev] lossless compression's limit : 53% ?

2014-03-25 Thread Nouvelle Collection
Hello, What is nowadays lossless compression's limit (tested on a large library of music samples, because of course, it depends on the music we do the tests on) ? I often see 53% - 62% of original WAV file's size. ( https://xiph.org/flac/comparison.html ) Are there algorithms that can losslessly

[flac-dev] [bug] --keep-foreign-metadata discards WAV cue markers

2018-05-11 Thread Nouvelle Collection
Hello, I noticed that option --keep-foreign-metadata discards WAV cue markers. Here is how to reproduce the bug: 1) Create a 24-bit 96khz in SoundForge8, add 20 seconds of silence, and add two markers with "m" key shortcut 2) Save it, compress it with "flac --keep-foreign-metadata testmarkers.wav"

Thank you very much, it works indeed with: flac -d --keep-foreign-metadata testmarkers.flac Suggestion for devs: 1) If a file has been compressed with "--keep-foreign-metadata", then make "flac -d" decompress the file with metadata *by default*, without having to also do "--keep-foreign-metadata
