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.
