YouTube’s new audio compression ruins dynamic range
It appears that YouTube implemented a new audio compression scheme that causes problems for uploaded video clips with a wide dynamic range (some acoustic guitar pieces for example).
People concerned about this issue are already sharing audio tips and tricks to fool (so to speak) YouTube’s compression algorithm by manipulating the recorded sound. A Wired article mentions one tip suggesting using an inaudible high frequency sound (think dog whistle range) in quiet passages, for example.
If you are planning to use YouTube to promote something which requires decent audio quality, you definitely want to learn more about this new YouTube audio compression scheme.
For more information and sample YouTube clips read the Wired article: New YouTube Audio Compression Stymies Uploaders. You can also view the original YouTube community forum thread that highlighted the problems.
