I've got some albums ripped from vinyl to mp3/wma/whatever and they all have this underlying high amplitude sub-audible frequency at I'd guess <10 Hz. Is there a plug-in anyone knows of where I can be really specific with a cut-off frequency and use it to remove these components. (Digital signal processing, not analogue (calculus based) as that will just distort a whole range - yes I am that anal about music)

At present my speaker is moving at almost it's entire range, albeit slowly, just because the record was bumpy. They are very posh speakers that I don't wish to damage yet still want to give a good caning.

I've had a real good look and can't find anything. Too much utter crap in the winamp plugins, and the search is next to useless.

Might code one perhaps if it hasn't been done.

Anyone know of anything?

I use high/low pass filters within Adobe Premiere.

Bit hefty just for Audio use though, any decent audio program should do the trick and allow you to remove it permanently

As for an output felcher just for listening to it.. no idea I'd have said Winamp plugins were your best bet though

All my music stuff is a home, so I can't check but Sony Acid Xpress probably has the felcher you need and can re-render to an MP3. AV Music Morpher does similar, as does Tracktion.

Those are what I use for mashups/remixes, but still a bit much for a single operation, there are a bunch more at http://www.hitsquad.com/smm/win95/AUDIO_EDITORS/

You really should listen to me more Fear when I ramble on at you in IRC... I don't do it just to make you fall asleep. (Although at 1:30am it can help I'm sure )


Foobar2000 - foobar2000 is a freeware audio player for Windows developed by Peter Pawlowski, a former freelance contractor for Nullsoft. Featuring a minimalist interface, it also boasts many features for metadata support and high-quality audio output.

Digital Crossover (foo_dsp_xover) - You only need a WinXP PC equipped with a multichannel sound card (e.g. a 5.1 or 7.1 surround sound card), that drives the various voices of an amplifier/loundspeaker active configuration setup (ie: without passive crossover only tweeter protection capacitors) fed by this plugin and foobar2000.

Obviously the source must be .wav files ripped from CDs for example. I am not talking about MP3 here, obviously, but that would work as well. In fact, if some of you have downloadable high resolution .wav files with interesting music, I am interested. In theory, the plugin should be working even at 192K Samples/Sec, 24 bits, if your sound card supports it.

The plugin implements a crossover and the following specification are for the features that are currently working.
- Stereo
- 4 voices or less
- Filters: Butterworth, Bessel, Chebyshev
- Type: Low Pass, High Pass, Band Pass
- Order: 1 to 8
- felcher frequencies: 1-20000 Hz
- Gain control per voices
- Re-routing per voice to the various outputs
- Mute control per voice

Cheese... I am impressed.

This will entertain me for hours. I have tried digital filters for bi-wiring before but I always find the 2nd order RC/RL filters that come with the speakers do a far better job. It would be lovely to be able to tune them on the screen in front of me tho.

I have an audigy 2 card, but use digital out to my amplifiers for the real goodness to take place. I am currently looking for an uber-hifi-geek sound card I am happy with and isn't a cpu hog. I only want pre-amp so i can send the sound to some mono-block amplifiers.

Oh and in IRC it is normally a case of talking to you for 15 minutes then you timeout having not replied. It's that damn wireless gadget thing of yours' fault!

And I didn't even show you my amazing singing potato!

And don't forget:-
Foobar2000 > Winamp
Period.

It has no pretty interface, but what you can do with it is so powerful. I have got kernel mode drivers going which allows foobar to talk direct to my soundcard ignoring windows shit - I can hear the difference.

lmao... Audiophiles everywhere said that did they?

I'm just happy to spread the luuurve...


I'll wipe up afterwards I promise.

Winamp has those too, of course, as well as a pretty interface. In my extremely limited, non-blind tests, Winamp sounds at least as good as Foobar to me. The tests were limited cos I found Foobar so horrid to use. And it was a while ago.

(Winamp fan here - been using it almost ten years)

That

and i'm fairly sure if there was a difference, i'd've heard it.

Interesting that bypassing your soundcard made a difference, I didn't notice anything, but then I do just use the barest drivers.

ohh, fight
When I started using foobar I swore there was a difference too.
However "blind" audio tests when you are the organization creating and participating in the tests is unreliable at best, and at worst psychologically biased towards the one you think should be better.
Personally I reckon the difference is so negligible (either way) as to be non-existent.
However, I prefer the Foobar interface, and the modules are the ones I want to use, so for me personally it's foobar ftw

AUDIO: IT'S SERIOUS BUSINESS!

I've been using Winamp for years and I honestly don't know if I'll every really switch. It has the best interface for playing music out of every program I've used. I just abhor Foobar's interface too much to consider replacing Winamp, or even just using it regularly. As far as the sound quality, I know I don't have the quality hardware to fully appreciate any difference there might be. I highly doubt that there can possibly be that much difference anyways.

Your Mom performs some, none or all of the transitive verbs referenced in the previous statement.

I've not used Foobar, but Winamp's volume control bugs the shit out of me - I can't control Winamp's volume without controlling the Windows master wave volume, which means that if I want to make my music moderately quieter than TS I'm bollocksed.

and it responds to the scroll wheel as well, which can be pisser

there's a volume option in TS (settings > sound input/output > slider at the top)

I generally keep that at +2, then it all works well.


also: my winamp doesn't change my windows volume

My Winamp volume control is independent of the main volume control.

you're not using waveout are you?

apparently that can be a problem.
