Hello!

I have a couple songs that have too-high frequency in some parts. The songs are great, but the high frequency parts actually hurt my ears.

Can your software level out the frequency of a mp3 song?

Please note that I'm looking for something that will level out the frequency across the entire song, without me having to isolate different parts of the song.

I just want the entire song to be the same frequency (pitch).

Thanks!

FordMustang,

What do you mean by filter? I tried to level out the song's pitch (frequency) using the filters, but I got no where. Am I missing something?

Thanks

Use a VST low-pass filter. Don't forget to tick the 'Processing' box in order to monitor the effect.

ChairmanOfTheBored,

Thanks for reply. But wouldn't a low-pass filter just remove any high frequencies (pitches)?

I don't want to cut out the high frequencies. I want to bring those parts down in frequency a bit.

Yes, that's correct regarding the low-pass.

Provided you mean "bring those parts down in volume", then try a high shelf EQ; for more control add a band of parametric EQ. Download ReaEQ and give it a try if you haven't done so already.

ChairmanOfTheBored,

No, I don't want to reduce the volume of some parts. I want to reduce the pitch of some parts.

I've tried my hand at a section-by-second pitch reduction, but I'm not happy with the results.

I guess I'm looking for some sort of application that will allow me to do this across the entire song:

When the frequency is above "X" Hz, reduce it to "Y" Hz.

I was hoping that the lower the frequency of the high frequencies thing was a typo. But since it's not, I tried this method:

1. Use a combination of high-pass and low-pass filters or a crossover to separate the high from the low frequencies.

2. Send the high bands through a pitch shifter set to -12 half steps (down one octave, so that it's in tune with the original).

3. Mix the shifted parts back in with the low parts.

Alternately, try using the original full-range audio with high-end reduced, not eliminated, and mix in the shifted parts.

Either way, this works better with instrumental music; voices tend to come out sounding like The Evil Dead.
