PlayoutFrequency(), at least, is called ~200 times a second. The others appear to not be in practice, but it's unclear what value they serve. They were traces before https://chromium-review.googlesource.com/c/518133/, which was more reasonable, as you could enable them for just audio coding traces. But now that they are just logs, they make all VERBOSE logging unusable.
