stjohn_piano 2020-08-09 no Recently, I found an ambience track that I quite like, which has helped me several times to sink into the undistracted trance-like state in which the best programming occurs. Details: - Title: "Rainy Night Coffee Shop Ambience with Relaxing Jazz Music and Rain Sounds - 8 Hours" - Link: hyperlink http://www.youtube.com/watch?v=c0_ejQQcrwI www.youtube.com/watch?v=c0_ejQQcrwI - Channel: Calmed By Nature - Date: May 3, 2020 I decided that I'd like to have my own copy. You never know when something will just disappear from the internet. Also, I didn't want the entire 8-hour track. 1 hour on a loop is fine, and takes up less space. Here's the approach I used: 0) Machine details. - Windows 10 - Windows Subsystem for Linux (WSL): Ubuntu 16.04 I'm using the WSL Ubuntu terminal. I already have the youtube-dl and ffmpeg tools installed. 1) Check the available formats on Youtube. youtube-dl https://www.youtube.com/watch?v=c0_ejQQcrwI -F 2) Choose a format number. Download the video. I chose format number 18 (mp4). youtube-dl https://www.youtube.com/watch?v=c0_ejQQcrwI -f 18 The downloaded file was named "Rainy Night Coffee Shop Ambience with Relaxing Jazz Music and Rain Sounds - 8 Hours-c0_ejQQcrwI.mp4". I renamed it to "ambience.mp4". It's 1.3 GB. 3) Extract the audio into its own file. ffmpeg -i ambience.mp4 ambience.mp3 The audio file is 443 MB. 4) Split the audio file into hour-long segments. The last segment will contain any left-over portion of the track. ffmpeg -i ambience.mp3 -f segment -segment_time 3600 -c copy out%03d.mp3 Source: hyperlink http://unix.stackexchange.com/a/283547 unix.stackexchange.com/a/283547 Note: The -segment_time value is in seconds. 5) Keep the first segment. Delete the others. Also delete the original ambience.mp4 and ambience.mp3 files. The first segment ends on a jazz resolution and some rain noise, which means it will loop without causing a distraction. If it had ended on a jarring note, I would have looked for a good ending point and used an audio editor (e.g. Audacity) to edit the file to end at that point. I can use the VLC media player to play it on a loop. The final file is named "out000.mp3". It's 55 MB. Rename it to: ambience_rainy_night_coffee_shop_with_jazz.mp3
