Episode: 3641 Title: HPR3641: Turntable audio capture Part 2 Source: https://hub.hackerpublicradio.org/ccdn.php?filename=/eps/hpr3641/hpr3641.mp3 Transcribed: 2025-10-25 02:37:51 --- This is Hacker Public Radio Episode 3,641 from Monday the 18th of July 2022. Today's show is entitled Turn Table Audio Capture Part 2. It is hosted by Archer 72 and is about 6 minutes long. It carries a clean flag. The summary is on Revised Previous Capture Scripts. Hello, this is Archer 72 and in this episode I will be your host revisiting some scripts that I was working on on Episode 35-07. I went to try them out on one of my records and the results were inconsistent so I decided to go back and try A record which provided a lot more consistent results. For one I was using Hardware Equals and a number and when at some point I moved the USB plug from the turn table and plugged it back in again. It didn't keep the hardware number. So I used A record dash capital L which gave me the hardware signature that I could use which would always remain the same. What I ended up with was A record dash dash device equals hardware colon, card equals codec comma dev equals zero, dash dash rate equals 96,000 which is 96 kilohertz, the sampling rate, dash dash channels equals two, dash dash view meter equals stereo, dash dash duration is 1500 which is a little bit over 23 minutes on that number after duration is in seconds. dash f space DAT is from one of the pre-selected format shortcuts and it's 16-bit stereo at 48,000, I made 48 kilohertz, you can correct me in the comments but I think that rate equals 96 kilohertz is overrides that DAT specification. Then it's dash dash file dash type space in this case wave and the value you're writing to for the wave file and that completes the command for capturing a wave file. The script for capturing and converting straight to FLAQ is almost the same except after the dash dash file type being wave that stays the same and then you pipe to FLAQ space dash space dash O and then the file name as a FLAQ. So now I could keep the album whole or split it in the tracks. Then FLAQ had done an episode on this very thing using Audacity with one change before it was in his version, it was analyzed and you go to Silence Finder and then continue from his instructions. Now it's analyzed in the Analyze menu and label sounds. I found a tool to do this as well except it's on the command line. The tool is MP3 split but it is spelled MP3 SPLT. The format for this command is MP3 split dash S dash P TH equals dash 40 for the decibels comma min equals 6 comma RM. The explanation for this in the article I read is dash S is silence mode activate silence detection dash P specifies arguments for the silence mode and I'm guessing that dash P mean parameters TH equals dash 40 is threshold level and decibels to be considered silence min equals 6 is minimum number of seconds to be considered as a split point and RM removes silence from the split files. What worked for me using a journey album as an example from YouTube was setting the threshold to minus 30 dB's and min split time as 0.5 seconds. On a couple of tracks this left three tracks together because there was not enough silence in between to recognize a new track so here I used M player to seek to where I could probably hear the silence and then used FFM peg to cut where the tracks were using FFM peg dash I track dot flack dash SS to seek to the point you wanted put a time code in dash two put your next time code in toward ends and then track cut on that flack. I found an interesting web page for when I was trying to find the best source material to download so that when I converted it to flack it was still good and the site is whiteegram.com and they have downloaders on the page for YouTube and Instagram and Reddit and several others. So if you're one like me that likes to keep some material offline this is the one to do it. That's all I have. I hope this was useful if there are improvements to be made please leave comments or even record a show of your own. Thanks for listening. Goodbye.
