Decky Recorder Fork

Using enhanced mic noise cancellation

Optionally, you can download an enhanced noise cancellation binary for better noise cancellation from https://github.com/werman/noise-suppression-for-voice. If you run the script below, the binary will be extracted to /home/deck/homebrew/data/decky-recorder/librnnoise_ladspa.so. The recorder backend will automatically check for this and will use this noise cancellation binary instead of the default cancellation if it exists.

# Download gpl-3 binary for superior denoising (cannot include in this repo as gpl)

# Define the URLs and file paths
denoise_version="1.03"
denoise_zip_url="https://github.com/werman/noise-suppression-for-voice/releases/download/v${denoise_version}/linux-rnnoise.zip"
denoise_zip_file_path="/home/deck/homebrew/data/decky-recorder/linux-rnnoise.zip"
denoise_extracted_file_path="/home/deck/homebrew/data/decky-recorder/librnnoise_ladspa.so"

wget "${denoise_zip_url}" -O "${denoise_zip_file_path}"
unzip -j "${denoise_zip_file_path}" 'linux-rnnoise/ladspa/librnnoise_ladspa.so' -d /tmp
mv /tmp/librnnoise_ladspa.so "${denoise_extracted_file_path}"

Once you do this, reopen decky recorder, restart the microphone toggle, and you should see options to change the noise reduction percentage.

Building

If you want to build this plugin in theory you only need to run make init first, fill out details in the .env file, and then run make it. You will need the following:

node 18 (I recommend using nvm)
jq
pnpm
python + pip
Docker

Readme from the original author of the repo marisaa999 below:

This plugin is heavily based on the Recapture-Plugin for Crankshaft from Avery: https://git.sr.ht/~avery/recapture In particular a lot of code for the gst-launch-1.0-command itself and the additionally needed dependencies were taken from the Recapture-Plugin.

https://git.sr.ht/~avery/recapture/tree/0fdbe014ec1f11bce386dc9468a760f8aed492e9/item/record.go#L19 https://git.sr.ht/~avery/recapture/tree/0fdbe014ec1f11bce386dc9468a760f8aed492e9/item/plugin/src/index.tsx#L161 https://git.sr.ht/~avery/recapture/tree/0fdbe014ec1f11bce386dc9468a760f8aed492e9/item/plugin/Makefile#L22

This plugin was made with the decky-plugin-template (https://github.com/SteamDeckHomebrew/decky-plugin-template)

Please do not judge my code, I am bad!

This plugin is still in WIP.

Thanks

Huge huge thanks to @safijari for fully implementing Rolling Recording/Replay Mode (https://github.com/safijari/decky-recorder/tree/rolling-record)
@Newbytee for pointing out that I forgot the "-e"-option in the gst-launch-1.0-command
Avery for the original Recapture Plugin
Epictek for inspiring me to setup a proper build process (https://github.com/Epictek/DeckyStream I found out about this plugin when I was basically already done q.q)
kleutzinger for fixing the file names and making it so it confirms with ISO_8601
DerpyChap for adding a few audio related improvements (AAC and Stereo)

Known issues

It seems like long recordings (over 30 minutes) dont get saved (marissa999/decky-recorder#2 (comment))
It seems like starting a recording while docked and outputting to a 4k monitor causes the Deck to crash (marissa999/decky-recorder#8)

FAQs

Can I save to the SD card / some other location?

This is not yet configurable through the plugin but yes. What you would do instead is

Move your Videos folder to the new destination (e.g. /run/media/mmcblk0p1)
Make a symbolic link (e.g. ln -s /run/media/mmcblk0p1 /home/deck/Videos)

Now it'll look like there's a Videos folder on your ssd but the data will actually be in the SD card.
