To add effects like reverb in a simple way without downloading convolution reverb files, we can just use sox. sox "in.wav" "out.wav" gain -2 reverb 40 50 40 text/html 2026-01-26T19:41:50+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.tonytascioglu.com/scripts/media/apply_eq_directly_in_pipewire?rev=1769456510 Apply Headphone EQ Directly In Pipewire I have DT770m headphones that need EQ to be decent. I used to use easyeffects but it required a lot of extra load. Pipewire already has a native equalizer (or can use LV2/LADSPA plugins). So, it made sense to just do the EQ in pipewire. text/html 2023-01-15T23:23:19+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.tonytascioglu.com/scripts/media/batch_convert_photos_to_jxl?rev=1673824999 Batch-convert files to JXL JPG and PNG are old. JPEG-XL is the hype new image format. It has many cool features which I won't exhaustively list here. <https://jpeg.org/jpegxl/> If you decide to convert your files, you will find cjxl can be slow on the slow presets. Also, compressing an image with multiple threads reduces compression ratio. text/html 2023-04-02T04:22:15+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.tonytascioglu.com/scripts/media/change_pipewire_sample_rate?rev=1680409335 Change Sample Rate of Pipewire Typically, most Linux sound servers run at 48000 Hz by default. This is a sane choice as most digital audio is 48 kHz. However, when I'm recording, I want Pipewire (and the Jack compatibility) to run at 96 kHz. Similarly when playing music, you might want to switch to 41000 - though I don't think I can hear the difference in that case text/html 2024-05-04T20:44:03+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.tonytascioglu.com/scripts/media/gstreamer_vaapi_full_range_color?rev=1714855443 GStreamer VAAPI with Full Range Color If you're using vaapisink with full range color, this is a mesa issue. I'll add the patch I made that you can use later. It's pretty hacky though, new mesa has a bt709-full matrix, but not a bt601-full, and the parameter supposed to mark it as full range doesn't work, so you may need to manually set it. text/html 2025-03-11T02:29:28+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.tonytascioglu.com/scripts/media/split_surround_output_pulseaudio?rev=1741660168 Split output on sound card (PulseAudio) I have a surround sound card in my system, currently an old Soundblaster Live connected over PCI. It has 3 line outputs, and 1 input. By default, if set to Stereo Duplex in PulseAudio, it only uses the main audio output, the green front headphone/line output. text/html 2025-03-11T02:27:57+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.tonytascioglu.com/scripts/media/stream_display_ffmpeg_netcat?rev=1741660077 Stream a video or screen to another computer using netcat There are a couple ways to use netcat with this. For example: server just sends, client receives when it wants to - very much like udp, or, server is on standby until receiver starts the connection. text/html 2025-03-28T02:30:36+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.tonytascioglu.com/scripts/media/stream_link_collection?rev=1743129036 Live Links So there are a few types of live links. 1) M3U HLS feeds These are most common these days. You send an m3u or m3u8 playlist file that keeps getting extended with chunks. Each chunk can be .ts or similar. Handles video and audio, useful since you go in chunks and can dynamically switch quality. text/html 2025-03-19T06:39:53+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.tonytascioglu.com/scripts/media/transcribe_video_text_subtitle_speaker_color?rev=1742366393 Transcribe Multi-lingual Video Into Subtitles With Speaker Color Ok I want to do a few things. * I have videos that are english, turkish or mixed. * I want a text transcript and subtitle files * I want to have subtitles colored per speaker * text/html 2025-02-25T09:31:15+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.tonytascioglu.com/scripts/media/turn_song_to_instrumental?rev=1740475875 Turn a Song Into an Instrumental Sometimes tracks with vocals are distracting, or, you want to explore the stems for fun (eg: listen to bass or drums). 2022 way: use spleeter I used to use spleeter (made by Deezer) pretty often, and it's decent spleeter separate -o separated_audio/ -c mp3 -b 320k -f "{filename}-{instrument}.{codec}" --verbose *.mp3
