Live, uncompressed music often has peaks that are 4 dB higher, or more, than a typical commercial CD. Such peaks are brief, and would not really affect the total size of the FLAC file. Really, the average level is what determines whether the FLAC file ends up being smaller than 50% as it...

...9;ve recently fixed some quality problems with very quiet signals (down to -144dB), ?so applications which need extended positive dynamic range can achieve it by adding before encoding and removing it after decoding without much quality compromise. The ability of CELT interconnected Jack to exceed 0dBFS is a functionality that I've personally depended on, because it allows me to stick a limiter before my final output and not worry about intermediate gain levels. Since this change in behavior (unlike our API changes) would be easily missed developers while causing intermittent terrible quality...

I always assumed that ov_read_float() would get me samples in the range of [-1,1), and anything below or above that can be clamped (or clipped in the final conversion to an integer format.) However, I recently saw this: https://github.com/LaurentGomila/SFML/issues/310#issuecomment-9974550 Apparently, there are Vorbis streams that use float samples with values in the range of [-32768,

Nicholas is probably right about noise. Another factor would simply be the amplitude of the resulting file. A 275 MB 24-bit file which compresses to 110 MB is probably not very loud. I assume that the average level is somewhat low, with few if any peaks that reach 0 dBFS. FLAC is very good at compressing audio that is not loud. In fact, the quieter the recording, the smaller the

Thanks for the replies! My first thought was that the file had low levels (before he sent me the file), but that's definitely not the case with this file. There are many peaks that reach 0dBFS. He sent me the original wav this morning and I loaded it into Wave Editor on OS X. I dithered to 16 bit using MBIT+ (high/ultra setting) and saved the 16 bit file. I did nothing else (no normalizing or any other processing). I can't give you the 16 bit size right now since I'm at work a...

Marvin, Ah, thank you for clarifying where "webroot" is. The application here will be a non-public stream with one listener client. Icecast is hosted on a computer at our radio station. It will receive a stream from a stream client at a remote live music event. There will be one listener: a media player running on another computer on the network at the station which will send the
