List of audio encoder types available via FFmpeg.

Typically used for exporting or streaming audio content in different formats. Each variant maps to a specific FFmpeg audio codec.

Value	Description
`'ffmpeg_aac'`	AAC (Advanced Audio Coding) encoder using FFmpeg. Widely supported across platforms; good balance of quality and compression.
`'ffmpeg_opus'`	Opus encoder using FFmpeg. High-efficiency codec commonly used for voice and streaming (e.g., Discord, WebRTC).
`'ffmpeg_pcm_s16le'`	PCM (Pulse-code Modulation) 16-bit signed little-endian. Uncompressed audio with moderate file size; excellent compatibility.
`'ffmpeg_pcm_s24le'`	PCM 24-bit signed little-endian. Higher-resolution uncompressed audio format, often used in professional audio applications.
`'ffmpeg_pcm_f32le'`	PCM 32-bit floating-point little-endian. Offers high dynamic range; used for precision in audio processing workflows.
`'ffmpeg_alac'`	Apple Lossless Audio Codec (ALAC) encoder via FFmpeg. Provides lossless compression; typically used in the Apple ecosystem.
`'ffmpeg_flac'`	FLAC (Free Lossless Audio Codec) encoder via FFmpeg. Popular open-source lossless format with good compression and widespread support.
`string`	Custom or unknown encoder type represented as a string.

Remarks

If a custom encoder is used that is not in this predefined list, it can be specified as a string.

Example

const audioEncoder: kKnownAudioEncodersTypes = "ffmpeg_opus";
