[SBE] audio problem

[Bruce Doerle]

Folks,

It is kind of funny, but very early this morning I had a similar problem.  Our weatherman uploads his weather reports into our FTP server in MP3 format.  These are ingested into our automation system automatically and then played on the air.  The weatheran uses Sound Forge to produce them and I have no idea what his setup is like.

But again this morning, but it sounded bad and distored on the air.  However, they sound fine in a stereo production studio. So I took the file and loaded it in Adobe Audition and combined into a mono file and you you could see the problem immediately.  So dumped the right channel and used the left to make a mono file for broadcast and replaced them in the automation system.  I don't know how he reversed the phase on a channel, but somehow he did.

Mr. Holmes:

I read the input about this problem. I have a more basic question.

You said the material sounds good in your studio and in the stations' control rooms. Is that in mono or stereo?

Remember that broadcast stations do not transmit Left and Right. They transmit L+R and L-R in order to get the mix for mono receivers.

As I understand it, the device you are using can introduce a variable phase delay. Signals that are slightly out of phase between Left and Right can sound fine in stereo, but will interfere destructively when mixed down to mono.

If you haven't listened to a mono mix down, give it a whirl and see how it sounds.

Good luck,
Dan Rapak
