Duration problem w/APL files
« on: May 25, 2004, 09:11:13 am »

I originally posted this over on the Monkey's Audio site, but knowing how busy Matt gets, I thought it might get a speedier response here (plus, it might be a MC10 issue...)

I have an APE file (& resulting CUE sheet) that was compressed with 3.99 (I don't remember which revision, probably the 1st). I imported the file into MC10. MC10 reports the file as "48.0kHz, 24bit, 2ch".
 
Dropping the CUE file onto the 3.99r4 MakeAPL application gave me the resulting APLs as expected. Importing the APLs into MC10 gives me the same format report. However, the durations are wrong. Here are the examples:
 
Original APE duration - 1:32:22 (reported by MC10)
 
APLs as listed in MC10.0.140
1 - 2:56
2 - 6:30
3 - 5:11
4 - 4:37
5 - 4:48
6 - 11:03
7 - 3:27
8 - 8:49
9 - 9:15
10 - 5:25
11 - 5:17
12 - 25:58
Total - 1:32:16 (done w/MC10 multi-select)
 
As determined by CUE file
1 - 3:12
2 - 7:05
3 - 5:40
4 - 5:02
5 - 5:14
6 - 12:01
7 - 3:47
8 - 9:36
9 - 10:05
10 - 5:54
11 - 5:45
12 - 19:01
 
Notice that all the APL tracks are significantly shorter than they should be (except the last one, which I'm guessing makes up the difference for the others).
 
Any ideas as to what is going on here? If you'd rather send people over to the MAC forums, please feel free to lock this thread and send folks to:

They're off by exactly the ratio of 44.1 khz to 48 khz.

Try recreating the APL files with the latest Monkey's Audio -- this should be fixed if you have 3.99 Update 4 installed. (maybe reinstall, and make sure IE's cache isn't getting you)

Thanks Brad.

Thanks for the input, Matt. I figured that there was some kind of sampling rate problem.

However, I had processed the APLs with 3.99r4. Nonetheless, I redownloaded & reinstalled. Same results.

Any other ideas?

Can you send the CUE + APL files (no need for the APE file) to matt @ jriver.com.

That'll let us know if the error is in the APL generation, or in the APL analysis by MC.

Thanks Brad.

Matt,

On a related note...is there any significant reason an apl wouldn't work with a flac? Seems like it should be possible.

10-27

To followup on this problem...it was one of a class known as PEBCAK (Problem Exists Between Chair And Keyboard).

The path was wrong for the FILE designator in the cue sheet. I'm not sure what logic MakeAPL uses, but basically, it couldn't look at the 48kHz files, so it defaulted to 44.1kHz sampling rate.

I believe a future version of MakeAPL will have better logic when hitting invalid FILE designators.

Thanks for your help!
