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.

wtv

WTV (Windows Recorded TV Show) is a digital video recording format developed by Microsoft and introduced in July 2008 with the Windows Media Center TV Pack for Windows Vista. The format was designed to replace the earlier DVR-MS recording format used by Windows Media Center, offering a more capable container for recording live television broadcasts. WTV files store video in MPEG-2 or H.264 encoding alongside multiple audio tracks in AC-3 or MPEG audio format, along with closed caption data, electronic program guide metadata, and copy protection flags. The container uses an internal directory structure that supports time-shifting features, allowing Windows Media Center to record content while simultaneously enabling playback from the beginning of the recording. A rich metadata framework preserves detailed program information from the electronic program guide (EPG), including show title, episode description, genre, ratings, and original air date, making it easy to organize and browse recorded content. The format supports both standard definition and high definition recordings from digital cable, over-the-air ATSC, and ClearQAM tuner sources. WTV files are natively accessible through Windows Media Center and can be converted to the simpler DVR-MS format using built-in Windows tools. While Windows Media Center was discontinued after Windows 7 (with limited support in Windows 8), WTV files remain in personal media archives and can be processed by third-party video tools.

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.
