I need a script that will take the last 0.050 seconds of audio from a batch of wav files and silence that 0.050 seconds. I have this ripping problem that leaves a click in my wav files (even when I uncheck that non-audio box)that have to be removed. Silencing that portion takes the least amount of re-save time. If anyone can show me how to make a script out of this I would be oh so grateful. Would this have anything to do with that "relative to cursor" function in the batch scripts?

Hi seanbaker, here's someone speaking.
Try this script:

Title: Cut50msAtEnd
Description: shrink waveform, cut 50 ms at end
Mode: 2

Selected: none at 0
cmd: Channel Both

cmd: Reverse

Selected: none at 0
cmd: Channel Both

Selected: none at 0
cmd: Generate Silence
1: 0.05

cmd: Copy

cmd: Undo

cmd: Paste Special
1: 1
2: 1
3: 30
4: 1
5: 0
6: 0
7:
8: 2
9: 0

cmd: Delete

cmd: Reverse

End:

If you don't want to cut the silence then delete the last "cmd: Delete" statement in script above.
Batch Run the script against the ripped files.

It seems to work except that in the mix/paste box, the crossfade checkbox doesn't seem to be scriptable. For this script to work properly, it needs to be unchecked. It seems to stay on whatever the last setting used was. Any ideas? Syntrillium, is this a bug?

You should not do any cut or paste operations in any script. Script is designed to help you modify the whole file. You can use it to normalize the whole file, not just a section of it. This is because when you select an area during script, it is actually taking into consideration the % of the file you selected.

So you want to delete the last 0.05 seconds of the file, you record a script to do this. But script recorded that you deleted the last 2% (or what ever) of the file. If your files are different in size, then CEP will delete different amount and it won't always be 0.05 seconds of the file.

Therefore, we recommend you do not hi-light a selection unless you hi-light 100% of the file during the script recording process.

Most features in CEP are scriptable, but not all of them. We currently have no list of what you can script and what you can't. The crossfade checkbox may be on of the features that is not scriptable.

I agree. It does work very well. If anyone wants to use this, you have to make a note to yourself to make sure the crossfade option in mix/paste was unchecked the last time used so that it will default to that. It seems like THAT should be scriptable. What Syntrillium said makes no sense, because your script defines an exact time by creating a 50ms piece of slience. That should remain constant no matter what the total length of the waveform is. In your script, after the 50ms of silence is created, it remains highlighted, so when it is copied, it will always be the same regardless of how long the total waveform is. Am I understanding this correctly? I've tried it on a number of waveform lengths and it always works perfectly. Thanks for the script. In reality the only fault with it is that CEP doesn't allow you to script the crossfade checkbox option, which seems to me a no-brainer. Maybe they'll fix this in the future. I've noticed too, that you cannot script the "paste from file" option either. Anyway, thanks for the script. It saves me a whole lot of time. By the way, I did edit the script for only 10ms. I noticed that most of my data click are around 7ms.

This script also works perfectly here on my system. Thanks for the heads-up, DD! And thanks to Sean for asking. I remember considering this one night, but only because I wondered what I might do when confronted with the same need. Since this has never come up, I promptly forgot about the whole thing until Sean asked.

I would concur that the checkboxes should also be scriptable. And Synt...you didn't REALLY think that us hacks out here would be of any mind to follow the rules, did you?

;-)

All the best... -Jon

I haven't tried it, but from inspection, it
looks like the above script won't work if the
current clipboard is set to anything other than clipboard 1. If so, to fix this, remove
parameter 9 from the Paste Special command.

Here's a tip. I have taken the part out of the script which deletes the silenced audio. Instead I leave it in there. The reason is it takes less time to resave. When you delete even a small portion of audio and then try to resave it, it has to flush the whole file first. On my system, that means an extra 15-20 seconds. When I'm running this on 25 files the time adds up. Besides I don't notice the extra 10ms of silence left on, would you?

Detlev Dalitz · Posted - Mon Jul 16, 2001 5:32 am

well, seanbaker,
at first I've tried to code a "cut", but there comes up an issue I don't remember yet.
So I've gone the save way with "copy undo".

Regarding your note of flushing the entire file I've un-checked the "Options / Settings / System / Force complete flush before saving". So saving of files works faster if only small portions of the file has been altered.

There is another option I like to have unchecked for that kind of sample precise operations:
"Options / Settings / Data / Smooth Delete and Cut boundaries"

By the way there comes up an idea:
I would like to have a "settings dump" feature, which saves the overall settings of all checkboxes, radio buttons and so on to diskfile. So if we plan to exchange some presets or other tricky stuff, I would say, hi, cepfan, load my base dump and play the script, afterwards reload your basedump.

Does cool.ini already contains those complete information?
