FFmpeg removed libfaac support in 2016 because the other AAC encoders are better. Use a different encoder.
Native FFmpeg AAC Encoder (-c:a aac
)
Use the native, built-in FFmpeg AAC encoder:
ffmpeg -i input.wav -c:a aac output.m4a
- Included by default in all
ffmpeg
versions. - Has many features, fairly good quality, supports the most channel layouts and sample rates.
- See more details and specific options with
ffmpeg -h encoder=aac
.
Fraunhofer FDK AAC Encoder (-c:a libfdk_aac
)
ffmpeg -i input.wav -c:a libfdk_aac output.m4a
- Provides excellent quality.
- Supports HE-AAC.
- Not compatible with the GPL, and therefore not often made available by distributors, so you’ll need to compile
ffmpeg
to use it. - See more details and specific options with
ffmpeg -h encoder=libfdk_aac
.
Apple AudioToolbox AAC (-c:a aac_at
)
- Only available for macOS/iOS users.
- See more details and specific options with
ffmpeg -h encoder=aac_at
.
Microsoft Media Foundation AAC (-c:a aac_mf
)
- Only available for Windows users with
ffmpeg
compiled with--enable-mediafoundation
. - See more details and specific options with
ffmpeg -h encoder=aac_mf
.
