Purpose

Add details in the audio Custom Formats description specifying which format is lossy or lossless.

Approach

Added details in the audio Custom Formats description specifying which format is lossy or lossless.

Here's a breakdown of whether each format is lossy or lossless:

Lossless Formats

  • TrueHD ATMOS (Dolby TrueHD with Atmos – lossless)
  • TrueHD (Dolby TrueHD – lossless)
  • DTS-HD MA (DTS-HD Master Audio – lossless)
  • FLAC (Free Lossless Audio Codec – lossless)
  • PCM (Pulse Code Modulation – lossless, uncompressed)

Lossy Formats

  • DTS X (Can be either lossy or lossless depending on the underlying codec, usually DTS-HD MA for lossless or DTS-HD HRA for lossy.)
  • ATMOS (undefined) (Atmos is an object-based audio format that can be paired with lossless TrueHD or lossy DD+.)
  • DD+ ATMOS (Dolby Digital Plus with Atmos – lossy)
  • DTS-HD HRA (DTS-HD High-Resolution Audio – lossy)
  • DD+ (Dolby Digital Plus – lossy)
  • DTS-ES (DTS Extended Surround – lossy)
  • DTS (Original DTS format – lossy)
  • AAC (Advanced Audio Codec – lossy)
  • DD (Dolby Digital – lossy)
  • MP3 (MPEG-1 Audio Layer III – lossy)
  • Opus (Highly efficient lossy codec)

Summary

For lossless audio, stick to TrueHD, DTS-HD MA, FLAC, and PCM.
For lossy audio, formats like DD+, DTS, AAC, MP3, and Opus are common.
DTS X and Atmos depend on the codec used underneath.
