Help for Prepare Linux Mint for Real-Time audio

Post by Codesound »

Hi,

i love Linux Mint Cinnamom and I would like to use this distro for my audio productions,
but natively Mint doesn't have anything for real-time audio processing. To prepare my Linux Mint Cinnamom 19.02 for this I need to:

1. Install the Linux low latency Kernel
sudo apt install linux-lowlatency

2. Configure real time access... Add your current user to the audio group:
sudo adduser USERNAME audio

3. And then give the audio group real time access: open terminal in:
/etc/security/limits.d/
With the terminal opened in this path, create audio.conf file
sudo touch audio.conf
Add this 2 lines to the file audio.conf:
sudo nano audio.conf
@audio - rtprio 99
@audio - memlock unlimited

4. Install pulseaudio-module-jack
sudo apt install pulseaudio-module-jack

5. Install from Ubuntu Software Center qjackctl when is required, allow qjackctl for real time process;

6. Set the CPU speed in Performance state;
(how I do it?)

7. Install Reaper Linux Version and configure it to work with Jack driver...

but I don't know if these are all the correctly steps for my purpose or if I forgot anything...

Please help me also to understand how to set the CPU speed for high performance...

I forgot anything? Please help me to understand...

Thanks for now...

The easy way (the kind of way I use whenever possible) is to install indicator-cpufreq. Gives you a simple way to switch between powersave and performance mode.

Should work anywhere indicator applets work--I'm pretty sure that includes Mint.
