NUV to M4A: Extract Audio from NUV(MythTV) Video to M4A(MPEG-4 Audio) with River Past Audio Converter, NUV2M4A converter, conversion

What is NUV?

MythTV is a Unix application which turns a computer with the necessary hardware into a network streaming digital video recorder, a digital multimedia home entertainment system, or Home Theater Personal Computer. MythTV is free software licensed under the GPL. It can be considered as a free and open source alternative to Tivo or Windows Media Center.

To convert MythTV NUV video to other formats with River Past software, please have MythTV DirectShow Filters installed.

What is M4A?

Because of its exceptional performance and quality, Advanced Audio Coding (AAC) is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is the audio codec of choice for Internet, wireless and digital broadcast arenas. AAC provides audio encoding that compresses much more efficiently than older formats, such as MP3, yet delivers quality rivaling that of uncompressed CD audio.

To encode MPEG-4 audio, you need to have River Past MPEG-4 Booster Pack in addition to your audio software.
