1. LOWER COMPRESSION BUT HIGHER CPU USAGE
2. NO COMPRESSION MODE TO SELECT

EDIT : But compared with Monkey's Audio, WMA still use more power.

WMA = 34.0MB = ~13% CPU Usage
Monkey's Audio - High = 33.7MB = ~7% CPU Usage

anyway, non-audio chunks can appear anywhere in the file, before audio chunks or in between two audio chunks.  a wave file can have multiple audio chunks; how do wavpack/MAC/optimfrog handle that?


Interesting how FLAC handles it.

I think you are still not understanding the WAVE spec.

there is a difference between the questions "1. how will FLAC the format handle it?" and "2. how will flac the command-line encoder/decoder handle it?"

1. FLAC-the-format is not a WAVE file compressor on purpose. RIFF WAVE is a container format, and it is not practical for a general-purpose lossless audio codec to try and store and recreate a container format, especially when it can only compress one of the many types of contained sub-chunks.

my comment about AIFF was tongue-in-cheek to try and lead you to this conclusion but failed. if a format completely supports RIFF WAVE then it must be able to store and recreate any RIFF WAVE file regardless of what it contains. but then why not then also support AIFF? and matroska? and soundforge files with audio and cakewalk .bun files? they are all containers used for audio, and different enough that they have to be hard coded into the lossless format.

so what will FLAC-the-format do with multiple linear PCM 'data' sub-chunks? merge them into one audio stream or treat them as separate chained streams.

2. what will flac-the-commandline do with multiple linear PCM 'data' sub-chunks? currently it will only encode the first one and tell you so. I've never gotten any complaints about that.

so what will wavpack/mac/optimfrog do, both as codecs and as tools? you didn't answer that.
