Tool For Testing: Akaizer Time Stretch And Pitch Shifter

[Cie]

@Djeroek

Good work Cie!
Is it possible you leave the tool gui window opened after pressing ‘process’? I often like to try different settings and having to keep opening the tool is a little irritating even though I can bind it to a keyboard shortcut.

Thanks, yes this is possible. I will have a look when I have time for it.

edit:
It also seems to always work on the complete sample, disregarding selection in the sample editor. Is this something that can be implemented, or a shortcoming of the akaizer.exe? Would be cool if it could work on just the selection.

No this is not possible unfortunately, only processing the complete sample.

@Djeroek

This is absolutely awesome. Earlier today I idly thought to myself, ‘Wouldn’t it be great if someone had emulated the akai time-stretch alogrithm and written a little app that processes wavs through it.’ So I Googled ‘akai timestretch’, and found Akaizer. Well how about that? Amazing. I processed Amen +1 octave and nearly wet myself at how good it sounded. My next thought was ‘I guess I’ll have to get used to switching programs a lot to process files then pull them back in. In a perfect world Renoise would have this effect as an option in the sample editor, man that would be sweet. Not gonna happen though.’ I thought I’d try to find some discussion of Akaizer, how people used it, whether people had found anything similar etc, so jumped on the renoise forum and to my joy the first thing that popped up was V1.0 of a 2.8 compatible Akaizer tool. So good.
It works exactly as it should, no bugs so far. I will continue the research.
Many thanks to Ben, Martin and Cie.

This is a very nice story! Nice to hear this feedback, it is a motivation for every developer. I am happy you have found this tool and like it.

It seems that if you only change the cycle length and do not touch the other parameters, the akaizer does not create a new file (means: it seems to have no effect).

Thank you very much, mxb. I think you should keep the ownership, I just added and fixed some things, you had the idea and did the main work. I have added my credits for the update to the manifest if you don’t mind. If the next version works stable I will upload it to the tools page.

I have created a new version (1.0):

• upgraded to akaizer latest version 2.1.1 (before it was 1.6)
• try to fix file not found errors
• a dialog appears if parameters are useless (akaizer did not generate a new file; e.g. if you only change the cyclic parameter)

Download Akaizer 1.0

Could you test it please? Works for me on Win7.

It works great, but after sample processing renoise stops responding on right mouse click and upper context menus also (Win7 x64, renoise 2.8.1)

No this is not possible unfortunately, only processing the complete sample.

Also not through some kind of hack, cut and process the selection in some kind of buffer and re-insert akaizer’s result back into the original sample? /> No worries if too much work, happy that it is working at all!

So Cie, I’m getting the message “The selected parameter combination did not have any effect.” regardless of the settings, any ideas?

It’s working perfect, but I’ve got Korsun’s problem as well.

For some reason Akaizer don’t process short samples.

@muckleby

So Cie, I’m getting the message “The selected parameter combination did not have any effect.” regardless of the settings, any ideas?

It can be avoided by adding some silence, but there’s gotta be some other solution…

And, btw, it would be nice if Akaizer could sync Time factor with Renoise’s beats. Like in Rubberband.
It’s a great tool already, it just needs some improvements. Please don’t abandon Akaizer

[esaruoho]

Does this work on Mountain Lion and what is the current stable install, please?

Good news for the Macintosh hardcore, got this working finally.

If you replace the Akaizer file in the tools bin folder -

yourusename/Library/Preferences/Renoise/V2.8.0/Scripts/Tools/com.mxb.Akaizer.xrnx

With the same file from the latest Akaizer CLI version -

You’re in business!

Out to Ben Burchett, MXB & Cie for the real work of course…

So I have the same error message as the people before:

std::logic_error: 'trying to load sample data from a non existing file: '/tmp/Renoise-17659/Renoise_TmpFile-0-6-100%_1000_-7.wav''
stack traceback:
[C]: in function 'load_from'
main.lua:71: in function 'process'
main.lua:128: in function 'show_dialog'
main.lua:139: in function <main.lua:138

I was getting that error message on Windows 8(hey, It was a fresh install on a new laptop I bought, I didn’t install it…it’s not bad though) and what I did is remove the comma in the path. It now works. I changed it to use the new Akaizer as well. Small things, but big deal for me that’s a programming beginner. I’m happy when I try to troubleshoot a problem for hours and resolve it.

Hi all,

I’m a recently registered user…was really looking forward to running this, but I’m getting an error too. Win7 system…renoise v3.0.1

std::logic_error: ‘trying to load sample data from a non existing file:\Renoise_TmpFile-0-7-168%1021+5_R.wav’’

stack traceback:

Hi, same thing, cant make this thing work under os x 10.9.5

i’ve tried this and its the same error over and over:

1. Failed to open the file for writing.

2. std::logic_error: ‘trying to load sample data from a non existing file: ‘/var/folders/nn/sr193vy54j91wq8646xqd0300000gn/T/Renoise-0-5221/Renoise_TmpFile-0-11-105%1000-16_R.wav’’

Quickly looking at this for you…looks like multiple problems to me

First the script itself. I’ve modified it for more error checking.

Secondly the version of Akaizer that people have in relation to the version of script.

Thirdly the permissions of the executable file for people running Linux or Mac OSX (doesn’t apply to Window users.)

Now an extra step for Linux and Mac OSX users… Because the tool is a zip file, file permissions on the main executable are lost so we will have to set it manually to make sure

On Linux or Mac goto a terminal and find the Akaizer executable and change directory to it. It should be around ~/.renoise/V3.0.1 (or V3.1.0)/Scripts/Tools/com.mxb.Akaizer.xrnx/bin/linux32/ or ~/.renoise/V3.0.1 (or V3.1.0)/Scripts/Tools/com.mxb.Akaizer.xrnx/bin/osx/

You need to now set the Akaizer file flags to executable. So execute the following command:

$ chmod +755 Akaizer

You’d have to give that a try
