Okay Thank you for that tracktion archive, and the TONS of help and ideas.

Question about the tracktion thing... I don't get it.

Okay so you have wet and dry ... the left and right going out there, then you have the left and right going in through ... mono? i dont get it.

lol. Maybe the next Betabugs product will be the MonstaWidener with just 1 switch: on/off, for the ultimate RonC effect ;)

I'd DL the RonC Widener....or a Winona Ryder.

Actually...

There's a one-knob widener already completed by BBA.

I shit you not.

Pretty much ready to go.

I've just replaced Orange Peel with mda image on the guitar in Impaired and Tire Swing (and just uploaded :D ). World of diff.

I'm surprised nobody has mentioned this in the thread: what you are hearing is most likely the effects of a signal processor @ the radio station, like an Orban. These things really mess with the tracks, applying multiband compression, mono-izing the bass, limiting, and a very recognizable stereo-widening effect. Since you mentioned you liked the sound of songs on the radio, I am almost sure that this is what you are hearing. For example, listening to song X on your cd player, you will notice a less dramatic stereo image than listening to song X on the radio (well usually).

Very good point, brianbrian..

Try putting your mixes through a Euphonix or an SSL. There is so much more headroom and width in a pro console.

the vst effect stadust is alleged to hit that fm effect.

Also try to listen to what you like on a cd for the proper mix/sound since some radio stations actually speed up the songs to fit in more commercials. Some people percieve the higher pitch as a louder and wider mix.

There's no simple answer to that I'm afraid, I will have to explain Mid / Side processing..

There is a technique for stereo mic'ing which uses this trick, and its a very good choice where mono compatibility is important (bear with me ;)) Basically the source is miced in mono in the normal way, but another mic, with a figure of 8 polar pattern, is positioned as close to the main mic as possible, at a perpendicular angle so that the sensitive lobes are pointing out to the sides, and the side null is aimed at the sound source.

The main mono mic is panned centrally as usual, but the figure 8 "side" mic needs to be added to one channel and subtracted from the other. The usual way to achieve this with a traditional mixer is to split the side mic to two channels, one of which is panned hard left, and the other panned hard right and also inverted.

The stereo width of the recording is determined by the level of the side mic, and inverting the left channel instead of the right will flip the stereo image round.

The main advantage is that mono compatibility is guaranteed, as summing L & R channels to mono will perfectly cancel out the "side" mic, leaving just the basic mono signal from the "mid" mic.

The implications of that are: stereo signals can be represented by Mid and Side signals as well as L & R, and it is possible to convert conventional L/R stereo to M/S stereo and back with no loss of information.

The first rack in that archive simply converts L/R stereo into M/S stereo, provides seperate volume controls for the M & S signals, and then converts back to L/R stereo.

Image

The top Vol / Pan controls the mid level. Notice this has both L & R inputs connected (summed to mono), and feeds both L & R outputs.

The lower Vol / Pan controls the side level. This has the left input connected directly, and the right input connected via an EQ filter which does nothing but invert the polarity. In other words we are subtracting the right input from the left to obtain the difference between the two. To convert back to conventional L/R stereo, this difference signal needs to be added to the mid signal for the left channel, and subtracted from the mid signal for the right. (I use another EQ filter to invert the polarity before adding the side channel to the right output).

Setting both Vol / Pan filters to -6dB results in no change. Muting the side channel results in a mono signal. Turning up the side channel however, will widen the stereo image, just like it did in the stereo micing example at the top. (see we got there in the end!)

ooh.. i'm not famliar if that's an interface.. more signal flow based art please..
