Is there a simple shareware/freeware utility that can either remove hiss or add
some bass to some of my mp3 files? Or do the existing mp3s have to be
converted to wav, and THEN operated on by some utility program, and then
reconverted back to mp3?

At any rate, are such utilities available? (I don't really need a complete
equalizer program though). I'd just like to remove some tape hiss, and
(secondarily, if possible) add some bass to an existing file that is really
missing it (was taped off a radio, I think)

adding bass is simple, when you play the mp3-file in windows
media player and switch on srs trubass.

Adding bass is simple enough. Any simple equalizer can do that, even
the one built into your windows volume controls.

Hiss is a completely different problem. Hiss is a complex waveform and
no simple program can remove it without also removing some of the
music. Basically, the simple programs merely set a cut-off frequency
and remove all sounds above that frequency. This only removes part of
the hiss and also removes part of the music. The complicated programs
work by identifying individual parts of waveforms and removing the
ones that you don't want to keep. If you are very good at setting the
program up, the results can be excellent. If you aren't, they are
crappy.

GoldWave is about the simplest program that I know of, that tries to
identify waveform parts. However, if you consider an equalizer to be
complicated, you'll probably never get GoldWave to work right.

It matters not how experienced you are, nor how dedicated to the task. If you're not having fun, you are doing it wrong.

Freeware-i wouldn't know, but one of shareware ones is Cool edit - great
program - you pick a sample of hiss in silent part and remove it from whole
track.
But adding bass can do almost any player, since almost all do have
equilizer, among others Winamp, Windows media player, musicMatch etc.

No - I meant rerecording the selection with the bass enhanced *in the
re-recording*, so that it will play like the rest of my mp3s.

I was thinking that DSP technology was advanced enough so that it could
identify the hiss (which is random noise) and subtract it out (that Fourier
noise pattern), without affecting the rest of the music. But perhaps it is
impossible.

I don't think I find equalizers complicated, it just that I wanted something
simple here. Meaning I don't need lots of bells and whistles. (Why use a
jackhammer when a hammer will do, so to speak).

Cooledit can actually subtract out the hiss from the entire track, without
losing the highs in the music? Really?

Well, i have Cool edit pro version and after you open track, you select a
piece of silence before music actually begins(there's only hiss, noise
etc.), then open filter and tell him that your current selection presents
unwanted noise, hiss (i believe you must click 0get noise floor')....Then
close filter (it remembers settings), select entire wave, open filter again
and click OK or preview. Filter then searches this waveform you choose
before through entire track and eliminates it. Results are quite good,
depending on settings you make. Just remember that you must tell him first,
what hiss is by doing like i described (it does say this in help section, if
you look thoroughly.).
Bad side of this is that you must have at least one section with no music,
just noise, no matter if it's at the beginning, at the end or in the
middle.. Longer this sectin is, better result will be.

If you decide to choose cool edit, you can do it from there, since it has
simple and advanced equalizer (Graphic and parametric ones). Just remember,
anything you do, it will cause your mp3 to be converted to wav, and after
edit is done, you'l have to convert it back to mp3. I think cool edit uses
fraunhofer codec - slow, but good. From my knowledge, it's impossible to
edit mp3 directly.

If you are referring to the one MS provides, the ACM installed audio
codec then:
It is slow and old and poor qual decoder compared to most newer ones
than it.
Decode it in something decent if you must apply effects to it in
Cooledit or whatever editor.
JukeBox Decoder is my own, doesnt use ACM, decodes mp3, has a 10band
EQ, but there are plenty others with better decoders than the ACM.

I don't know which one. I think it's installed together with adobe audition
alias cool edit. It says only mp3PRO (FhG).mp3. And it says fraunhofer IIS
copyright 2000-2003 Adobe systems incorporated. I think it's not old.
Anyway, LAME can easily be downloaded from almost anywhere.

Thanks. I'll try to find CoolEdit - not the pro version, but the somewhat?
limited, free download version (2000), if I remember right.

AFAIK, CoolEdit was never free. If you can't find one, just use Goldwave -
you can do exactly the same thing in exactly the same way. It is shareware
too but uncrippled more or less.

I found CoolEdit 2000, Goldwave 4.26, and Goldwave 5.06, but haven't installed
any of them yet.

Are they all about the same, in terms of removing hiss and being able to add
some bass? And in ease of use, and limitations of the shareware versions?

I know CoolEdit only lets you do 2 things at a time (in the shareware version),
but don't know about any limitations in either of the two Goldwave downloads I
got.

Was just wondering what the big difference is between CoolEdit and Goldwave
(either version)???

I use ExactAudioCopy's "Process Wav" function to reduce hiss. Sample a
section of pure hiss (usually from before music starts or after music ends)
to be used as the noise pattern and remove it from the entire file.

It may not be an ACM codec then, in which case it is likely newer and

For Decoding it'd be a better choice than an ACM but many decoders
are.
