Releases of FDK AAC Packet Decoder

1.24.5 current version, released on: 2025-10-16

Changed frame dependency calculations to use the actual stream format instead of assumptions
Made frame dependency configurable so potential seek errors can be solved manually without requiring a new component
Restored %codec% back to AAC for USAC profile
Added %codec_long% tech info
Added AAC frame length tech info reporting for files that don't use the standard 1024 samples

1.24.4 released on: 2025-10-15

Further increased maximum frame dependency to fix more errors on seek.

1.24.3 released on: 2025-09-12

Restored multi-channel support.

1.24.2 released on: 2025-09-11

Updated FDK-AAC library.
Increased maximum frame dependency to fix errors on seek.

1.24 released on: 2022-01-31

Updated FDK-AAC

1.23 released on: 2021-05-07

Fix maximum packet dependency reporting, now it will properly decode files with two immediate playout frames together at the start
Revert a change to the math defines in libFDK-AAC, fixing compliance

1.22 released on: 2021-05-05

Rewrote first packet analyzer to feed into the decoder when both are used
Removed internal delay removal code, as nothing should be using it anyway

1.21 released on: 2021-05-01

Fixed first packet analyzer to correctly apply limiter configuration, so that decoder delay is correctly reported, especially with the default configuration of PCM limiter being disabled

1.18 released on: 2021-04-15

Fix SBR configuration display for USAC files

1.17 released on: 2021-03-25

Restore PCM limiter level threshold to 0.1 dB from maximum instead of 1.0 dB

1.16 released on: 2021-03-24

Change reset after seek to completely dispose and recreate the decoder to hopefully prevent seeking from triggering packet loss concealment

1.15 released on: 2021-03-23

Updated libfdkaac to latest snapshot
Changed first packet analyzer to allocate its own decoder instance, so packet concealment and stream flushing don't get in the way of stream start IPF

1.14 released on: 2020-11-10

Correctly indicate USAC as codec rather than codec profile
Leave off codec profile if it is identical to codec

1.13 released on: 2020-08-30

Added support for short frame AAC
This is the last version to work on Windows XP

1.12 released on: 2020-06-15

Restrict to only LD, ELD, and USAC
Fix AAC Audio Object Type parsing
Fix end of stream handling

1.10 released on: 2020-04-27

Re-enable PCM Limiter, now targeting -0.1 dBFS with an attack delay of 5ms for USAC files, and 0 dBFS with an attack of 15ms for regular AAC files
