Articles / Re: Routing signals directly to SignalScope using Soundflower
« on: January 12, 2010, 12:27:11 AM »
I installed and was using SoundSource before I started having issues with SignalScope. I'd set SoundSource 'Input' to Soundflower and then set SignalScope's input to the same, so that's why I asked earlier about how SignalScope handles inputs, I wonderd if I'd used SignalScope to override something which caused this issue. I have noticed that if I go to Device I/O, that both 'Line In' and 'Soundflower' are switched on. I'd also selected Soundflower as SignalScope's output when Soundflower was working correctly, but I remember that SignalScope's output was selected to 'Built-In Audio' when I was having issues.

I'll have a further poke at this later on, see if I can pin a sequence of events down.

Edit: after poking, I found that if I start SignalScope Pro directly (i.e. by not calling my saved project), then select Soundflower as my output via SoundSource and Soundflower as SignalScope Pro's input, i.e. *not* a system-wide input via SoundSource, then I get my signal. When I look at Device I/O, I notice this:

- In my saved project, when I start it, both 'Line in' and 'Soundflower' are turned on.
- In the new project, only 'Line in' or 'Soundflower' is turned on, depending on the selected input on the main control panel.

Edit2: In my saved project, 'Line in' and 'Soundflower' are both activated only if 'Soundflower' is the selected input.

Hi Ben,

Sorry for not responding quickly, I thought I had set this to email me if someone responded.

To answer your questions:
1. Yes
2. 10.5.8
3. I have SoundSource (from Rogue Amoeba) to help me switch between inputs and outputs. Normally yes, Line Out would be my default output, but SoundSource can change this. An example: if I use SoundSource to switch from Line Out to Soundflower and then restart, Soundflower is selected as the 'default' output upon reboot.
4. Yes
5. 44.1kHz
6. No

A note: I had used Soundflower for this task before and it worked, so I'm not sure what changes I made broke it.

I've been looking at this a bit more. I have restarted the computer, set up Soundflower so that it is sending signals correctly (confirmed with LineIn from Rogue Amoeba), then started my project. I had previously saved it so that inputs and outputs were set to 'Built-in Audio'. As soon as Signalscope starts, there is a double-pop from my speakers and the sound fades. How does Signalscope interact with inputs and outputs?

I'm using Soundflower 1.5.1 to run signals from Quicktime Player 7.6.4 to Signalscope Pro 2.1.5. I have had an intermittent problem where I can no longer get a signal to Signalscope through Soundflower (line-out works fine). I recently did the following: started Quicktime, selected Soundflower (2ch) as output and tested OK, then started Signalscope via a saved project - and Soundflower cut out. The standard fix for this (so far) is a restart of the computer (a PowerPC G5 iMac).

Would anyone be able to help out at all?

SignalScope Pro / Length of capture
« on: December 28, 2008, 09:26:32 PM »

I'm using SignalScope Pro to analyse the noise from a process which continues for at least 12 minutes. I previously used SignalScope 1.8.4, where I could record a spectrogram for 15 minutes. Is there any way I could record a spectrogram for longer than the current 20 seconds?
