Waveform in editor (in 9.5.0 / 10.1.0)

[SimnaWeb]

I am currently teching a show which uses a lot of music for transitions, which means I only really use about a minute of the songs but I don't want to edit them down. I am also running this on an older box; P3 256mb ram. This causes a problem when trying to quickly run through the editor. I constantly have to wait for the waveform to reload or else I risk freezing the system.

All that setup, now here is my request. Could there be an option to turn the graph off by default but add a button where the graph would be to turn it on temporarily until we change the screen? It would greatly help performance on slower machines.

Let me know if that doesn't make sense. I just got out of a very stressful rehearsal.

That is certainly feasible. This already happens for audio files of greater than 10 minutes duration, so it wouldn't take much to add a user preference in which you could request only manual displays of the graph, regardless of the file duration.

Mike, you're amazing. That would make life a lot easier.

Anyone else dealing with anything similar? I don't want to be the only person asking for this and getting it (if Mike decides it be so).

I agree with this one also. In experimenting with putting our current show on SCS, I have a 40 minute rain storm track and 10 minute wind track. When I pulled up the 40 minute track and nothing displayed, I wasn't sure if the editor had hung ... so an indicator there would be useful. And the 10 minute track does take a bit of time to display.

Mike, if you could provide an option to allow us to specify the length limit, above which you would display an activation icon in big black region where the wave form usually sits, that would probably do the trick and provide flexibility and be most intuitive for the users.

Thanks. John

... and for users who want all manual display of waveforms, they could just set the limit to zero ...

That's a bug which I'll look into. There should have been a button displayed labelled 'Display Graph'.

Hi

i too am experiencing this delay - yet when i use gold wave on the same machine it is not such a problem - i think this program saves the 'display' in some way after initial scan (presumably with some info to check if the source file is dirty). would this have the potential to speed things up and keep the display?

just a thought

Mike,

Found an example of a peak file algorithm:

Some useful info in these links. The option to scan once and save display information to a peak audio file should certainly speed up re-display. I'll look into this.
