I suspect it uses N-1 frames dropping last frame, thinking that 26 ms is not actually much audible and does not affect quality of listening. Why? this is good question to the developers of the Audacity. Could be feature or bug :) | |

If two frames are used, the same duration (~26.122 ms) is used, and if N frames are used (N>2), total duration is 26.122*(N-1). What may be the cause of this? Where can one find the description of this headers byte-by-byte? | |
