hi all,
i have a few questions about aac.
firstly, how to encode aac from line-in (like LiveInCode0.94, which support only mp3,ogg,flac & speex) - i'm searching this forum and didn't got a clear answers - i want to record audio from FM-tuner directly to aac and minimize steps from FM->wav->aac to FM->aac
and secondly, how to split aac without recompression (like mp3directcut, looking for spectrum and using cue). for example, i want to split my 8 hr. live-record to single tracks.
thanks, encoder that i use is neroaac (q 0.42), extension is m4a
no one knows?
how to split aac without recompression
I have the same question...
Whether exists Encoder (frontend) for iTunes AAC except an iTunes-player?? It is desirable, that the device took not enough place.
Me too... How to split AAC/MP4 without transcoding/re-encoding?
MP4Box (http://gpac.wp.institut-telecom.fr/mp4box/)
Edit:
Windows user: The latest version of MP3DirectCut (http://mpesch3.de1.cc/mp3dc.html) (2.16 , released today) supports cutting of AAC ADTS streams.
I think ffmpeg will do this without transcoding, though I am not completely sure what happens precisely at the breakpoint. Try
ffmpeg -i infilename.m4a -ss 00:03:00 -t 00:02:00 -acodec copy outfilename.m4a
which will copy the two minutes from 3 minutes 0 seconds to 5 minutes 0 seconds. The -i specifies the infile, the "-acodec copy" specifies that the output file should copy without transcoding the audio stream (audio has "acodec". There is also -vcodec for video and -scodec for subtitles ...)
I agree with previous message that mp3directcut is probably you best choice for editing. You might also want to look at "Besplit."
