Jokosher 0.11.5 Review

Jokosher was discovered while trying to add audio to the Image Favicon Video. Audacity would not run on my Fedora 13 Desktop Computer. Audacity gave me this error “Expression ‘stream->capture.pcm’ failed in ‘src/hostapi/alsa/pa_linux_alsa.c’, line: 3653“.

Jokosher was installed and I was able to use it without reading the manual or help file. The video was finished after recording my audio and adding the amplify filter in Jokosher. Once the video was uploaded, I read the help file and manual. Some more filters were installed.

Jokosher is a free multi-track audio editor from There are downloadable packages for Linux and Windows. It is very easy to use and never crashed while in use.

The record button was very smooth because it starts recording immediately. By default, Jokosher will overwrite parts of the track while recording, therefore always use new tracks for re-recording. The voice quality on the non-name USB microphone was good and the output did not require any effects except amplify. Trimming and Removing portions of the audio was very fast.

In conclusion, Jokosher is a great audio editor. It quickly enabled me add and edit audio for the Image Favicon Video. Recording audio with Jokosher was easy because it correctly detected the default system settings. highly recommends.


  1. For lower quality microphones and audio inputs, use the mono amplifier.
  2. Use Minimal Mode for screencasts or podcasts.

    Nice blog. Really, I think that most audio and video devices can be USB. What happens if you connect too many audio devices hooked to one notebook?
