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.

rmvb

RMVB (RealMedia Variable Bitrate) is an enhanced version of the RealMedia container format developed by RealNetworks, introduced around 2003. While the original RM format used constant bit rate encoding, RMVB employs variable bit rate compression that dynamically allocates more data to complex scenes with high motion and detail, and fewer bits to simpler passages like static shots or fade transitions. This approach yields significantly better visual quality at equivalent average file sizes compared to the constant bit rate predecessor. RMVB gained particular popularity in East and Southeast Asian markets during the mid-2000s, becoming a widely used format for distributing full-length movies and television content in regions where bandwidth was limited but viewers still demanded reasonable picture quality. The format typically uses RealVideo 9 or RealVideo 10 codecs, which drew on technologies comparable to H.264 in their compression approach. RMVB files support embedded subtitle streams and multiple audio tracks, making them practical for multilingual content distribution. The container retains the streaming-friendly architecture of RealMedia while delivering the quality improvements that variable bit rate encoding provides. Although RMVB has been superseded by MP4 with H.264 and other modern formats for most purposes, it retains a user base in Asian markets and can still be found in online media archives and personal video collections from the mid-2000s era.

aiff

AIFF (Audio Interchange File Format) was developed by Apple in 1988, drawing its structural design from Electronic Arts' IFF standard. As an uncompressed audio container, AIFF stores linear PCM data at full CD quality — typically 16-bit at 44.1 kHz — preserving every detail of the original recording without lossy encoding. The format organizes content into chunks that can also carry metadata such as markers, instrument definitions, and comments. Professional audio engineers on macOS frequently rely on AIFF because it guarantees bit-perfect fidelity through every stage of editing and mastering. One significant advantage is zero generational loss: unlike MP3 or AAC, repeated saves never degrade the signal. Another strength is seamless integration with Apple's professional tools, including Logic Pro and GarageBand, where AIFF serves as a native working format. The container supports multiple sample rates and bit depths up to 32-bit, accommodating high-resolution workflows that exceed CD-quality specifications. For anyone prioritizing lossless integrity over storage efficiency, AIFF remains a dependable choice across the recording industry.
