Audio glitching means crackling, popping, and other sound problems. They can occur for a variety of reasons.
Glitches after instream ads¶
Glitches after instream ads can occur if bit reservoirs are used in the encoder. If an MP3 file or stream is encoded with bit-reservoir feature enabled then the consecutive frames depend on each other. In the case of in-stream ads, the stream is cut exactly at the trigger point. During this process, dependent frames in the stream can be separated and heard as glitches.
