Re: Need help

Re: Need help

^^^ what he said...

but what you have posted looks fine, so far.

there are a few other factors to consider.

Don't think so, but it looks weird.

I'm pretty sure that one changes audio sources multiple times during the recording, hence why it looks weird.

Re: Need help

The SA in Audacity is pretty useless.

You need to an app like Cool Edit Pro 2.x or Adobe Audition to see the blockies.


That said, I think the first SA you posted is probably ok, but the second looks like it may be lossy.

the 2-3 second span is important, though.. you can't really see well enough when viewing the entire span of the track.

if you can't get a better SA to post, you can always just post a track and one of us will have a look, no problem.

Warning: This happens to be the concert that Dime was shot. The shots are audible in the recording.

G'day Elochai. The sample you provided is made up of 4, possibly 5 different sources. Check attachment.

Re: Need help

As for this being lossy; not sure. Haven't seen this spectral before. It has definitely had some work done to it but don't know what.

Below is a 2 second grab.
