at3_to_aa3+smpl.bms
Changes an AT3+ (Atrac 3 plus) header to a valid OMA header (*.aa3) and automatically extracts the smpl area if there is one available (that's the loop points). This is the format used by most of the PSP games and seems also common among PS3 games. The resulting files can be decoded by Sony SoundForge or sometimes played by KMPlayer. The *.smpl files may be injected in decoded wave files again with my smpl_inject (link see first post). However the sample transition at3:wav isn't 1:1 so the loop points are biased and only serve as a help when editing tracks. If somebody could help me adjusting the loop points, that'd be awesome!

What if the at3 files have no header? i have encountered some of these.

Thanks for the script anyway works great

Thanks alpha.

However it does not work for a standard stereo 48hz file i tried. Not sure if it has to do with regular atrac3 or atrac3plus. Also this file has a MSF header at the start.

http://www.megaupload.com/?d=PYD76HDL

[AlphaTwentyThree]

func_header_AT3.bms
This is a header adder function for standard RIFF at (no AT3+).
Note that Atrac files only have 66, 105 or 132 kbps. If you don't know which one of them they have, you'll have to try out, I haven't found a way to distinguish between them. As always, you'll need a headerless file.

Code: Select all

# Add an Atrac RIFF header to data. 
# Needed variables: OFFSET, SIZE, BITRATE, FREQ, CH
# Note that mono atrac files are non-standard and automatically saved as stereo.
# To get the original file, decode the stereo at3 to wav and change the channels via hex.

The following two scripts are for transferring the loop points from PSP and PS3 AT3+ files to decoded wave files. Background: AT3+ needs to be traversed into OMA first to decode it with Sony SoundForge which deletes the looping cues. Use the first script to extract the cues from the *.at3 files, then write them to the decoded *.wav files with the second script. It will overwrite the files. Note that the looping cue isn't at the very right spot as I don't know how the AT3 samples are represented in the decoded WAV. It's some ms off, but if it's not at the very beginning of the stream you'll get the idea about where the cue should be.
The second procedurecan also be used to inject a *.smpl file into any wave file with the same name. If that wave file already has a "smpl" are in the header, the script automatically saves the old one as *.smpl_old and substitutes it with the new.

Thanks alpha worked with haze.

now we just need to figure out how to parse the interleave segments and an at3 file.

[AlphaTwentyThree]

Just corrected the XA deinterleave script: viewtopic.php?f=13&t=4450&p=40777#p40777
Now recognizes correct stream stops.

I tried use scripts and at3 converter, but SoundForge still believes .aa3 and RIFF .at3 files as empty:

Regarding your uploaded samples: all *.mft files can bee converted with the above script. I've also looked at the other two files:
- SND0.at3 is standard AT3+ and has to be turned into an *.aa3 with my at3toaa3.bms script before you can open it with SoundForge.
- The Audio.at3 can be parsed with the script in the next post. It's a headerless AT3+ file. The script transforms it into an *.aa3 file so that SoundForge can open it.

[Researchman]

Audio.at3 obtained through this program http://ifolder.ru/19566825 (get from ps3ripkits.com)

This program can convert .pmf psp movie files and .pam ps3 movie files(if rename to .pmf) to uncompress .avi(video) and .at3(audio).
