The codec to encode the audio track. Codec "Without reencoding" copies the audio stream from the input file into output without re-encoding if possible.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
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.

AVCHD (Advanced Video Coding High Definition) is a high-definition recording format jointly developed by Sony and Panasonic for use in consumer and semi-professional camcorders. Announced in 2006, the format records H.264/MPEG-4 AVC video at resolutions up to 1920x1080 with Dolby Digital or uncompressed LPCM audio, stored within an MPEG-2 transport stream container. AVCHD was designed to work with a variety of recording media, including optical discs, hard disk drives, and solid-state memory cards, giving camera manufacturers flexibility in hardware design. The use of H.264 compression delivers superior image quality at lower bit rates compared to earlier recording standards like DV and MPEG-2, enabling longer recording times on the same storage capacity. AVCHD supports progressive and interlaced scanning modes, accommodating both cinematic and broadcast-style shooting. The directory structure follows a strict specification that includes playlist files for navigating recorded clips, making it compatible with Blu-ray players when recorded to compatible disc media. An enhanced version, AVCHD 2.0, added support for 1080/60p progressive recording and 3D stereoscopic video. The format remains widely used in the camcorder market and continues to be supported by major video editing applications.

ra

RealAudio is a proprietary audio format developed by RealNetworks and first released in 1995 as one of the earliest technologies enabling real-time audio streaming over the internet. During the dial-up era, RealAudio was genuinely revolutionary — it let users listen to audio as it downloaded rather than waiting for the entire file, a paradigm shift when a three-minute song could take 30 minutes to transfer. The format evolved through multiple codec generations: early versions used low-bitrate speech codecs for 14.4 kbps modems, while later iterations (RealAudio 10, built on AAC) delivered near-CD quality. RA files support constant and variable bitrate encoding, adaptive multi-bitrate streaming, and buffering algorithms designed to minimize playback interruptions on unreliable connections. At its peak, RealPlayer was installed on hundreds of millions of PCs, and broadcasters like the BBC and NPR relied on RealAudio for online streams. A lasting technical contribution was the adaptive bitrate streaming concept that influenced later standards like HLS and DASH. Though supplanted by modern codecs, vast archives of RA content from early web radio still exist and need conversion for playback on current devices.
