Steps to edit recordings:
 * Find the recording in the Excel list and put your name as Editor before starting to edit it.
 * Remove Noise with Noise Removal Effect (Effect > Noise Removal)
 * Use Analyze -> Silence Finder to find silent parts to use as input for noise removal
 * However, using default noise reduction 24 db the result was that you could hardly here anything. I reduced it down to 6 to be able to listen.
 * Use High Pass filter with cut-off 25Hz to remove subsonic noise (Effect > High Pass filter )
 * (Try the notch filter, didn't use it yet) Effect > Notch filter
 * Use Normalizer with only the middle selection (Effect > Normalize)
 * Remove unwanted sections which contain offtopic conversation etc. (Select the section and Ctrl+X (Cmd+X on Mac) )
 * Zoom in and scroll over the file to find peaks
 * Listen to the peak
 * If it's voice which is just too loud, mark the area (use Z to start/end with zero crossings) apply Amplify Effect with -2 to -4 to reduce the loudness.
 * If it's a click, use Click Removal effect or cut it out completly. Use Fadeout/Fadein effect to smooth the end/start of a click within a word
 * When done, check the file again
 * You may now use Amplify/Normalizer/Equalizer to improve the audability of the voices. Euqalizer didn't work for me though.
 * Export to OGG when finished
 * Use Quality 5 (Options Button in the Export)
 * Fill in title, author and track
 * Rename to remove spaces. Replace everything apart from a-zA-Z0-9 with underscores
 * Upload to wikimedia.org
 * use the CC BY-SA license
 * Update the Wiki Page to include the recording, example: Scrum Session with Recording
