You may have problems putting that on YouTube or SoundCloud : they have automatic copyright-infringement detection, see ... https://support.google.com/youtube/answer/2797370

That's a very reasonable position to take and one I will bear in mind.

Oddly, I don't agree. People assume the more the merrier, but in backups, if you make them too complex, you stop doing them, or worse, miss versions and processes. The sweet spot between No Backups and Too Many Backups is two. Main and Protection Copy.

WAV and FLAC content is exactly the same and just wastes time, effort and drive space. Use WAV, full stop.

Making low quality copies for posting or other production is completely up to you. If one of those goes face-first in the mud, you can always make another from one of the two perfectly quality WAVs. Or, I think you addressed this up the thread, make a copy of the archive MP3 (for example) if you made archives of the MP3s.

Good archiving advice which I will follow.

Well I am up to speed now and have transferred a number of playable tapes with some success thanks to the feedback from this site. The non-playable ones will need some further work before I attempt to play them as they are suffering from tape shedding and sticking. Still about 30 tapes to go - some recorded at 1.75 ips so potentially a lot of material!

I have a very quick and almost embarrassing novice question. When I first started this project, I clicked the record button in Audacity and off it went and recorded the input audio fine. On the horizontal audio level displays I could check the audio levels (to make sure they were correct and not clipping or be too low for example) as the 'vertical' recording bar swept from left to right, when it reached the right hand side of the screen the twin-level display would leap leftwards slightly so that I could continue to monitor the recording levels in real time - as the recording went along so as to speak.

But now for some reason something has changed with this display and I must have obviously accidentally changed something. Now when the vertical bar sweeps across to the rhs of the display it disappears off the rhs of the screen and I can no longer monitor the recording levels - I have to grab the moving bar at the bottom of the screen and 'yank' the display towards the lhs side of the screen to see where I am in real recording time and what the levels are.

I have tried looking at the manual but cannot see the 'trick' to get this back. In essence, all I want to so is to continually monitor the recording levels in real time - all the time - on the screen. Any help in getting this facility back would be most welcome.

Many thanks Trebor - just the job. What a great product Audacity is, and what a great forum this is to support it. Thanks again.

Another quick question if I may. I have looked at the on-line manual and the answer is not obvious to me.

I have ingested a tape that only has audio on the left hand (lh) channel and that is how it has been ingested by Audacity, However, I would like to 'mono' it up and make the right and left channels identical. In other words I would like to copy all the audio ingested to the lh channel over to the rh channel. Unless there is a different way to achieve this? Any help very welcome as ever.

Use the drop-down menu on the left of the track Split Stereo to Mono.
[X] Delete the dead track.

A Mono sound track will play audio to both left and right speakers and takes half the digital space as two-track mono which is what you asked for. You will never get "stereo" with, for example, violins on the left.

If you still want two track mono, Control-D duplicate your single track. From the drop-down of the top track, Make Stereo Track.
