Settings

Bitrate per channel: Set the Opus audio bitrate per channel. If set to "Custom", the Opus audio codec supports up to 256 kbit/s per channel with a recommended range of ≥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 AMR

amr

Adaptive Multi Rate

This format was originally intended for voice compression and is able to change the bit rates of encoded audio data. AMR is actively used for encoding and decoding voice while its being transmitted over network channels. The format allows one to consider network capacity and adapt it to channel loads. Due to this, the voice quality is practically undiminished.

OPUS Converter

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.
