Way to artificially introduce highs into old recording?
Bit of a newbie when it comes to this stuff, as this question will no doubt
reveal. Basically, I've got some old recordings (audio tapes, LPs, even CDs of poorly-mastered material) that exhibit an annoying absence of high frequencies, making them sound just too dull. I'm after whatever process, plugin, or whatever there is out there that can analyze such recordings and guess, with reasonable accuracy, when to add highs, and what type.. that sort of thing. I suppose this primarily means white noise. Better than nothing. This would be essentially the same sort of restorative process as anti- clipping, only something that works on the frequency spectrum. I'm sure something along these lines exist, but since I lack the basic knowledge of what terminology to apply to this scenario, I'm at a loss. Any takers? Thanks! |

Way to artificially introduce highs into old recording?
The Virtos Band Extrapolation filter will do what you need (mostly). If used
with the Waves L2 filter in hi res cd mode the results are much improved on old recordings. Use them with sound forge or other audio app of your choice.

PSPs MixTreble is awesome for this kindof stuff.

You might also look for an Aphex Aural Exciter. There were several models, both
pro and consumer. |

O;-) This would be essentially the same sort of restorative process as anti- clipping, only something that works on the frequency spectrum. Anticlipping has some decent options for guessing what it should have looked like when fixing a clipped peak. With this venture however you are in my unexperienced opinion more likely to get good results by using a combination of eq and gating ... the latter, in narrow bands, being what digital nr is about. I'm sure something along these lines exist, but since I lack the basic knowledge of what terminology to apply to this scenario, I'm at a loss. Any takers? Previously the default swiss army knife to recommend would have been CE2k with studio and noise reduction plug-ins. Adobe want you to pay for the full Audition package instead of getting only the half of it you need and have discontinued the "small" hobbyists version. Thanks!

I suppose this primarily means white noise. Better than nothing. Your first task is to get the best possible transcription you can, so that you have something to start with. With tapes this means careful riding of the azimuth. With LPs, this means using a fineline stylus and fiddling with the VTA to get the best possible tracking on the groove. With 78s this can mean trying out a lot of different sizes of stylus to find a portion of the groove that still has some detail left in it. This would be essentially the same sort of restorative process as anti- clipping, only something that works on the frequency spectrum. I'm sure something along these lines exist, but since I lack the basic knowledge of what terminology to apply to this scenario, I'm at a loss. Any takers? What you are thinking of is something like the Aphex Aural Exciter, which adds artificial high end by synthesizing harmonics of the original signal. If used lightly, it can be a real help in this sort of job, but only when all other things have failed. If overused, it can be really obnoxious. --scott -- "C'est un Nagra.

I'm sure something along these lines exist, but since I lack the basic knowledge of what terminology to apply to this scenario, I'm at a loss. Any takers? One approach would be to apply metered amounts of nonlinear distortion. Nonlinear distortion is the kind of distortion that can add tones that weren't present in the original recording. The name of the game is to add back missing harmonics in a way that most closely approximates the means by which they are generated by voices and musical instruments. This requires some experimentation, because what works for one piece of music and listener may or may not work for another. Here's the basic approach: I'm going to express the process in terms of Adobe Audition because its what's on my desktop and the audio editing program that I'm most familiar with. Another program with good potential for these kinds of manipulations would be Goldwave, with its ability to process sounds with math equations. A free trial version of either program can be downloaded from the respective vendor web sites (see google). For your demo, first take a piece of music and convert it to 32 bit format. Then chop off the high end at say 3-4 KHz. In Audition, the FFT filter can be programmed with a steep cutoff, or one of the low-pass "Scientific Filters" can be used. Then make a working copy of this file to play with. First use edit, copy to put a copy of the file onto the clipboard. Then use edit, mix paste with the modulate option to modulate the file with itself, one or more times. Each time you modulate the file with itself, you up the order of the nonlinear distortion being applied to the file. You'll probably lose some amplitude, but you can get that back with the amplification or normalization tool. This results in a file that is composed of more-or-less pure distortion. Then use the edit, mix paste tool to add one or more undistorted copies of the file back to itself to dilute the distortion until the file has the desired character. You may want to normalize the file to restore its loudness to the point where its' level is roughly comparable to the original. Finally, compare the "enhanced" file to the origional to see if you are pleased with the results. |

Way to artificially introduce highs into old recording?

m Bit of a newbie when it comes to this stuff, as this question will no doubt reveal. Basically, I've got some old recordings (audio tapes, LPs, even CDs of poorly-mastered material) that exhibit an annoying absence of high frequencies, making them sound just too dull. I'm after whatever process, plugin, or whatever there is out there that can analyze such recordings and guess, with reasonable accuracy, when to add highs, and what type.. that sort of thing. I suppose this primarily means white noise. Better than nothing. This would be essentially the same sort of restorative process as anti- clipping, only something that works on the frequency spectrum.
