Programming and Development New Plug-Ins

All you have to do is importing it, select all (Ctrl+a or similar), call the plug-in and hit enter.
The settings should be “Remove Vocals”, Strength 1.0, low-cut 120, high-cut 9000 or alike

.
Exactly what I did. Remove vocals doesn’t work (I also tried with your last excerpt)

What operating system are you working on?

Your (somewhat terze) description indicates that the audio isn’t processed at all. That’s a very unusual behaviour and there are only a few reasons that seem plausible, such as:

  1. Audacity is paused but you would not be able to call the effect GUI in this case.
  2. Wrong selection; it’s too short, somewhere without vocals etc. That’s why I said “Ctrl+a”, use Cmd if you’re on a Mac.
  3. Processing is aborted manually. The effect takes some time to process and one has to wait for it to finish. Do you see the progress bar?
  4. Abortion due to lack of memory. Seems highly improbably but nevertheless possible. Normally, Audacity would simply hang in this case.
  5. An error occurs during execution. As written earlier, try the debug button instead of the OK button and post the output.
  6. The audio isn’t stereo anymore due to some problem with the importer. Choose the “Analyze” action from the plug-in and tell me what the correlation value amounts to.
  7. Some forbidden character within the plug-in file - not likely to occur in two different versions of the plug-in though.

In summary, we need

  • Operating system
  • Screen shot before plug-in call
  • Text from the debug output.
  • Correllation value from “Analyze”.

This should suffice for now.

ok, let’s see:

I’m on Linux 64-bit (Ubuntu and Mint). The plugin doesn’t work on neither of the two distros.

On both plugin versions I’m using the default settings: for the “old” version Remove Vocals, Return Audio and Effect parameter 0.0; for the “slim” version Remove vocals, strength 1.0. On both plugin versions the lower and higher frequency cut points are 120hz and 9000hz

  1. I’m not sure what you mean by Audacity paused but I can call the effect and change the settings so I guess this is ruled out?
  2. I selected all of the clip you gave me, as seen in this picture:

  1. Yes, I see the progress bar. It takes about 25 seconds to complete for the last clip
  2. Audacity has never crashed or frozen while applying the effect
  3. If I use the “old” version I get “Peak ratio Input:Output for the first 200000 samples: 0.944515”. If I use the “slim” version I get nothing, absolutely nothing.
  4. Pan position: 0.171831, left and right channels correlated by about 65% (it says it’s a good value)

Tell me if you need any more info
Thank you

Ok, so it is actually all green.
I have no idea what’s the matter.

I hope that one with a Linux system (e.g. Steve) can redo the test and confirm that it is a Linux problem.

Does the old effect (Vocal Remover) or the “Classic” setting work?

The Audacity version 2.1.1 makes use of the newest Nyquist library, thus it is possible that it will work then.

85

Steve Daulton’s Vocal Remover (which inverts one channel and mixes the two as mono) works.
Not sure what you mean by “classic setting”.

I’m also waiting for 2.1.1 to come out

86

Testing with

This is the result:

In short, it works fine here. I’ve no idea what Starkiller2 is doing wrong. Will test on an older version of Audacity shortly.

87

Maybe I’m using the “wrong” Audacity version? (2.1.0)

88

Tested (same procedure as in previous post) with Audacity 2.1.0 alpha Feb 8th,
Same result - works fine.

89

What do you mean “you get nothing”?
Does the waveform disappear?
or do you mean that you get no noticeable change from the original pre-processed track?

90

I mean if I click on debug instead of OK (as Robert told me to do), I get no text in the nyquist output box

91

It has just been released, it seems.

Robert

92

It is the Action choice “Remove Center Classic: Mono”.


Gale

93

It is the Action choice “Remove Center Classic: Mono”.

There’s no such option. Only “Remove Vocals” and “View Help”

94

Then you are not using the Vocal Reduction and Isolation Effect. Get it here vocalrediso.ny.

See here for how to install Nyquist plugins on Linux: Missing features - Audacity Support.

Then choose Effect > Vocal Reduction and Isolation… .

What versions of Ubuntu and Linux Mint exactly are you using? Where did you obtain Audacity 2.1.0?


Gale

95

Sorry Starkiller, my fault.
The classic option has been prepared for the release version only.

No need to download it separately as you’re going to try out 2.1.1 anyways.

Robert

96

Thanks for pointing out Robert

Gale, I’m using Ubuntu 14.04 and Mint 17.1.
I got Audacity 2.1.0 from “ppa:ubuntuhandbook1/audacity”. I tried to compile it myself it but after 2 hours of waiting I got an error and gave up.

97

The above works for me on Ubuntu 14.04 64-bit in Audacity 2.1.1 RC3 using that specific vocalrediso.ny from the Forum or the shipped vocalrediso.ny (I am not sure if there is a difference between the two).

In 2.1.0 release on Ubuntu 14.04 64-bit (the same build and environment that Starkiller has), those two vocalrediso.ny files appear to process the audio but leave it unmodified. But on Ubuntu 14.04 32-bit using 2.1.0 release, the vocals are almost entirely removed (so it works correctly).

Does vocalrediso.ny depend only on Nyquist 4 which was first supported in Audacity 2.1.0, or on Audacity 2.1.1?


Gale

98

It worked fine for me with Audacity 2.1.0 alpha Feb 8th,

99

Presumably a 32-bit system, though?

Do you find as I did on 64-bit Ubuntu 14.04 that vocalrediso.ny does not work in Audacity 2.1.0?

If so you could try compiling the 2.1.1 source tarball ( Redirecting to: https://www.audacityteam.org/download ) on Ubuntu 14.04.

If you do so it may be best to first uninstall the packaged Audacity 2.0.5 version if you have that, and to uninstall the Ubuntu handbook PPA.

Before ./configure and make to build the 2.1.1 tarball, run:

sudo apt-get build-dep audacity

and:

sudo apt-get install cmake
