Voice changing Software for a ALSA only setup?

I was thinking about streaming sometime and want to change my voice a bit for anonymity. The programs I have looked at are lyrebird, and qjackctl and have realized after fumbling around like the idiot I am that they both require pulseaudio. I don't have it activated on my system for uhm, reasons? I have installed vox, jack-rack tap-plugins, and apulse. If I could configure vox with alsa that would be great but I don't and can't find a guide for that so I require assistance. I can't quite recall but I think I had trouble with both alsa and pulseaudio installed on my system and activated at once and I don't want to go through that debacle again.
Thank you in advance.

Re: Voice changing Software for a ALSA only setup?

Just get PulseAudio working. It's not that hard and the Wiki covers pretty much all possibilities. qjackctl is not a voice changing software, it's something completely different: it's a front-end for the JACK sound server, which, unless you configure it properly, will interfere with PulseAudio. And lyrebird *requires* PulseAudio, assuming you are using the AUR package, so it all points back to rolling up the sleeves and getting PulseAudio working.

Uhm...

E: [pulseaudio] module-rescue-streams.c: module-rescue-stream is obsolete and should no longer be loaded. Please remove it from your configuration.
E: [pulseaudio] main.c: No such profile: output:analog-stereo
E: [pulseaudio] main.c: Failed to initialize daemon due to errors while executing startup commands. Source of commands: /home/joseph/.config/pulse//default.pa

I hope starting pulse audio doesn't break the system, last time I updated the system I had to take it to the shop because my wifi card was not in the mainline kernel tree.

Re: Voice changing Software for a ALSA only setup?

Who/what created your ~/.config/pulse/default.pa? Did you copy that from /etc/pulse/default.pa into your home folder? If so: why?

PulseAudio Wiki wrote:

By default, PulseAudio is configured to automatically detect all sound cards and manage them. It takes control of all detected ALSA devices and redirects all audio streams to itself, making the PulseAudio daemon the central configuration point. The daemon should work mostly out of the box, only requiring a few minor tweaks.

The "command" to start PA is described in the Wiki, you have to read that in its entirety since it answers all of your last four questions/concerns.

I can't read very well. I tend to skim and skip important steps. Thank you for pointing it out.

Gave up on this. supposedly pulseaudio " should work mostly out of the box, only requiring a few minor tweaks." but I'm just not willing to go through the hassle of misconfiguring daemon.conf, default.pa, and pulse and finding out all output and input audio devices is still muted for some odd reason.

Re: Voice changing Software for a ALSA only setup?

You can try a pipeline using arecord, sox and a virtual device like this. You'll have to find out the exact setup on your own, though.

Re: Voice changing Software for a ALSA only setup?

Now that pulse audio is installed I get these random shutdowns when I leave my computer to suspend while it's downloading something. It's irritating because it doesn't actually go through with downloading.

Re: Voice changing Software for a ALSA only setup?

There's close to 0 chance that this has any relation whatsoever. If you want downloads to happen just prevent suspending (... you aren't downloading during a suspend regardless). And even if it was, this is a bug in the kernel.

What's much more likely that you updated the kernel, it does have an actual bug, an you correlate this to pulseaudio, which doesn't make much sense.
