Is there a simple way to convert .trp streams to .mp3 audio format?
Converting HD Video Transport Streams directly to MP3 Audio Files (.trp to .mp3 conversion) is certainly possible and relates to users attempting to extract the audio track (MP3) from a TRP transport stream.
You can use one of several media editing programs or conversion utilities, such as Nero Recode or SUPER, which allow users to import TRP streams and export their extracted audio track in MP3 format.
