Audio Priming - Handling Encoder Delay in AAC
https://developer.apple.com/library/archive/documentation/QuickTime/QTFF/QTFFAppenG/QTFFAppenG.html
Decoder delay is the number of “pre-roll” audio samples required to reproduce an encoded source audio signal for a given time index. For AAC this number is typically 1024 and is algorithmically based. This is in contrast to …

All coded audio data is directly transmitted after the header. Therefore an encoder can start to transmit one frame immediately after encoding it. The delay is shifted to the decoder that has to wait until one complete frame plus the current state of the bit reservoir has arrived. Note: The bit reservoir delay of a variable frame

pass through an encoder and decoder and do not include transmission delays or a return trip. Note: ISO / MPEG Layer II produces a delay of 6X the frame length, which varies with the sampling rate used. At 48 kHz sampling, the delay is 144 mS. At 32 kHz sampling, the delay is 216 mS and at 24 kHz sampling, the delay is 288 mS.

Double-click on your primary audio device to bring up the speaker/headphones properties dialog, and navigate to the “Advanced” tab: At the bottom of this dialog, locate the option labelled “Allow hardware acceleration of audio with this device” and uncheck this option. By default, this will be selected, causing the problems described above.
What is decoder delay? And why? - HydrogenAud

DECODER DELAY AT START OF FILE: All *decoders* I have tested introduce a delay of 528 samples. That is, after decoding an mp3 file, the output will have 528 samples of 0's appended to the front. This is because the standard MDCT/filterbank routines used by the ISO have a 528 sample delay. It
