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.

wmv

WMV (Windows Media Video) is a family of video codecs and associated file format developed by Microsoft, first introduced in 1999 as part of the Windows Media framework. The format encompasses several codec generations, from the original WMV 7 through WMV 9 (also standardized as VC-1 by SMPTE under the 421M specification). WMV files are typically contained within the ASF (Advanced Systems Format) wrapper and use the .wmv extension to indicate video content. WMV 9/VC-1 achieved compression efficiency comparable to early H.264 implementations, delivering good visual quality at moderate bit rates and earning adoption for HD DVD and Blu-ray disc content as an approved codec. The format was deeply integrated into the Windows operating system, Windows Media Player, and server-side streaming infrastructure, making it a natural choice for enterprise media delivery, corporate training videos, and Windows-centric web content throughout the 2000s. WMV supports features including interlaced video, multiple bit rate encoding for adaptive streaming, and digital rights management through Windows Media DRM. The Silverlight platform also used WMV as its primary video format for rich internet applications and streaming services. While the industry has largely moved to H.264 and HEVC for most applications, WMV remains present in legacy enterprise content management systems, archived media libraries, and workflows tied to the Windows Media ecosystem.

voc

VOC (Creative Voice) is a digital audio container developed by Creative Technology and introduced alongside the original Sound Blaster card in 1989. It served as the native audio format for the Sound Blaster family during the DOS era, when Creative's hardware dominated PC audio. VOC files are block-based: each file consists of typed data blocks that can carry 8-bit unsigned PCM, 4-bit and 2.6-bit Creative ADPCM, 16-bit signed PCM, as well as A-law and mu-law encoded audio. This block structure also supports silence intervals, repeat loops, and marker points, giving game developers fine-grained control over sound playback. A notable advantage was hardware-level decoding — Sound Blaster cards could play VOC data directly via DMA transfer, freeing the CPU for other tasks in an era when processor cycles were precious. The format saw extensive use in DOS games from id Software, Sierra, and LucasArts. With the rise of Windows and the WAV format, VOC gradually fell out of mainstream use, yet it remains important for retro gaming preservation and for anyone working with vintage PC audio archives.
