While we're here, do the meter overload indicators extinguish themselves yet? Koz

For this particular subtask you may want to consider using Brian Davies' excellent ClickRepair tool - it costs a little but is well worth it if you have many LPs to transcribe. You can have 1 14-day free trial to see how it works for you. Brian is a retired Australian mathematician who some years ago was undertaking the same task as you, transcribing his LPs. He realized that he could write some very focussed tools to help him with the clean-up tasks - the results of CR are a little shy of magical imo (and I listen on fairly high-end kit QUAD electrostatics ELS-57s)

Immediately after capture I export a 32-bit float WAV. I then process this through ClickRepair and then import the repaired 32-bit file back into Audacity for all further processing. See this sticky thread: http://forum.audacityteam.org/viewtopic.php?f=28&t=1994

This step also leaves you with an unprocessed raw-capture 32-bit file for archive backup should you require that.

You may also find this suggested workflow tutorial from the manual useful: http://manual.audacityteam.org/o/man/sa ... ation.html

Hello waxcylinder,

thank you for your suggestions and for the link to the workflow an the thread about ClickRepair. I'm doing my transcriptions pretty much the way you suggested it and as it is described in the manual.

I discovered ClickRepair just recently and I'm using it for a couple of weeks. Currently I'm using fairly low settings in ClickRepair, which leaves a single Click or Pop now an then and for the moment I rather remove these manually instead of increasing the ClickRepair settings. But I'm still in a process of try and error with ClickRepair.

Cheers
Christian

Christian,

I used to do my repairs manually, originally with the Draw tool in Audacity and then with the Repair effect when that become available - but I found that was taking far too much time and was extremely tedious.

I find Brian's default settings a little too harsh - after much experimentation I use:

DeClick = 30 (Brain's default is 50)
DeCrackle = off
Pitch Protection = on
Reverse = on
Method = wavelet
Automatic = All (after initial use I now trust it to do its job)

The reverse is a cute trick to avoid the false positives of the rapid attacks you can get with percussives. Brian's s/w looks ahead and buffers the reverse so you can still hear the results (if required) as is playing normally forward. One of the things I really like is the ability to choose: raw signal, output, noise or none. The "noise" is particularly useful as it helps you ensure you are nor removing too much real signal (music). Of course it runs much quicker with Sound Output - none.

I know what you mean ;)

I will try your ClickRepair settings and see what happens.

Thanks again!
