EQ on sound files

[TimmyP1955]

The suggested method of cross fading a radio is to have two linked identical cues running at the same time, routed to different devices/speakers, one faded down and one faded up. The cross fade is achieved with two level change cues. It should be possible to process one of the files, in Audacity for example, to give you the EQ effect you want, as long as the file length (number of samples) is unchanged.

A possible caveat is that as the two files crossfade, the differing EQs could cause comb filtering, resulting in unexpected/unwanted tonal changes during the crossfade. I don't know what the actual likelyhood is, but.....

BUT: Let's say we have an analog audio console, and on the radio channel that feeds the house we have a digital compressor such as a Rane C4, OR on the radio channel that feeds the monitor we have a digital EQ such as a Rane PEQ55. Owing to the latency in the digital gadget, there is a very high probability that we will have comb filtering during the crossfade. Been there, and wondered "WTF?" for a moment or two.

I think an EQ change + crossfade in SCS would be a safer bet.

If we have a digital console, might we be able to use SCS MIDI cues to change the EQ on the audio console? I don't know what kind of MIDI console control is possible other than scene recall - ?

Plug-in support, for the application of various effects in "real-time", i.e. at the time of each individual cue playback, sounds like a potentially useful feature. I certainly wouldn't speak against it, unless it were to compromise system performance (added overhead) or software stability (complexity).

The ability to dynamically apply and tweak such effects is alluring, but I'll point out that the the same plug-ins can be used to great advantage to modify the each cue's audio file, prior to playback, using an audio workstation or editor program. I use Audacity, which is a very capable and free sound editing program, that supports these plug-ins. The only disadvantage I see to using a separate sound editing program to apply effects to separate versions of the audio files is that you can't dynamically tweak the effects without going back into the editor program, potentially starting with the unaltered (original) version of the audio file.

There's often more than one way to skin a cat, so to speak, and we should all be aware that the theatre sound designer's toolbox most often contains a variety of tools, each specialized to a specific purpose.

i'm sceptical of adding effects to the program, especially vsts where there is no certification, or guarantee of functionality.
SCS's primary function is as a reliable a sound cue playback source, and vst's add the potential for instablity- mike can't check if the hundreds of vsts out there will work with scs or not.

i've always been happy enough to create two audio files- one normal, and one eq'd and run them together, creating level changes cue where necessary

perhaps i'm being a luddite,
just my thoughts

of course, i meant skeptical rather than sceptical...

oh and also 'primary function is as a reliable sound cue playback source'

damn proof-reading...

Although there would be some fiddling needed to control the plugin parameters from SCS, I think. Maybe via Midi send commands!?
