Settings

Bitrate per channel: Set the AAC audio bitrate per channel. For example, stereo audio with 128 kbps set here will produce a 256 kbps file. If set to "Custom", the recommended range is ≥64 kbps.

Audio Channels: Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).

Frequency: Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.

Convert to OPUS

opus

Opus (audio format)

Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end ARM3 processors. Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC, and HE-AAC.

M4A Converter

m4a

Compressed Audio File

This is a lossless-format (and encoding algorithm) for Apple platforms. M4A is widely used in iPod players and as a component in QuickTime media-players. The m4a codecs decoder is found in open sources - this allows third party users to open files in that format.
