hello,
i want to archieve my audio cassettes to mp3. i have a terratec dmx 6fire soundcard and a good tapedeck, so all i need is a good software. i have recorded a tape now and wanted to filter out the hiss (is it called so?). i have first used the internal denoiser of cooledit, but this bad tune remainded: http://membres.lycos.fr/wstbrln/Untitled.rar
Then I heard of the plug-in from Sonic Foundry, the DeNoiser Plug-In. Because it isn't very cheap, i first wanted to ask the professionals here which denoiser is REALLY good.

Not having RA installed, I can't play your file, but the CE denoiser is not that bad, so I suspect your problems are more likely due to over-processing, than not using the correct software.
It is a common fallacy that, because it's digital, there are free lunches available. This is simply not the case! Any processing you do will have an adverse effect on the sound quality - the advantage is that the artifacts introduced are (normally) less offensive than the problems you are trying to remove - and it's a case of trading one against the other.
BTW, you should refrain from using the word 'ripping' when referring to transferring analogue audio from a tape. Ripping is a very specific process (where digital is extracted directly from a CD) and the use of the term in this context merely serves to confuse the less knowledgable.

There is more tham a little information about effective/proper aplication of NR in the CoolEdit forum. It has been discussed various times over the past year, with emphasis upon techniques that work and don't work. How the noise profile is produced, and how it is applied, will make major differences in results. In many circumstances it can produce a major improvment with no penalty.
The Sonic Foundry plug-in can produce good results. Sometimes it is probably better than CoolEdit's NR, sometimes not as good. It also needs a bit of understanding in order to be applied properly; it does not automatically give good results.

You are aware too that MP3 is a lossy compression format? For the uninitiated that mean is throws away most of the original file on the assumtion that it won't be heard. In head to head tests an MP3 will alway be different than the original (though the differences are really hard to find at the very highest MP3 rates). Please keep your original format recordings when using MP3. You never know when a better format will come down the pipe and you'll want to switch to that.

Hi, I'm very informed about Lossy Encoding, I'm a active member at Hydrogen Audio ;)
I ounly wanted to know about the Noise Reduction thing. Well, I will try to translate your answers tomorrow, I'm from germany  , but thx very much.

just beginning so I hope I'm enjoining this properly---- I also am trying to transfer "books on tape" to cds and have pruchased Magix Audio Cleaning Lab 3.0 and it does a good job (from my limited experience) of removing hiss etc--- my requirements are for voice so hi quality music may be differant--- MY request for info is I need to find
1.a faster way of making the transfer as now I have a tape recorder plugged into my laptop sound card which downloads to my desktop file through the Lab but does it at the same 45 min per side.--I was told there was a user freindly and economical attachment similiar to a usb zip drive that you put your tape in and it downloads to a desktop at ultra high speed and when burned to a cdr it plays at normal speed--??
2.at 45 min per tape side it also requires a full 80 min cdr for each side -- is there a way to compress so more can go on a single cdr?
any help would be much appreciated

I suggest you download a copy of CE2000 from this site - after you've used that for a while, you'll never go back to Magix. It certainly is not so good at music and you will find the increased flexibility of CE will make for a better job in the long term.

Well... yes there are some high speed replay devices, but I don't think you'll want to pay the sort of money they cost. The faster you move the tape, the more important the electronics and the mechanics become, so high speed machines are an expensive option. If I were you, I'd stay with the 1:1 transfer.
Apart from anything else, it does give you a chance to monitor what it really sounds like on the way in.

Yes and no.
There's a whole host of compression algorithms for audio. MP3 is currently 'flavour of the moth' but that could easily chage over the next year or so. MP3's are 'lossy' systems - they actually throw away a lot of the original material (this is done is such a way as not to be too noticeable).
There are a few 'lossless' sytems as well - Monkey's Audio comes to mind - and they will keep every nuance of the original, while making the files somewhat smaller (but not as small as lossy compression can achieve.
The disadvantage with all these compression methods is that you will end up with a CD which can only be played on a computer (although there are some 'normal' players on the market which understand MP3). This massively limits your end-market - so it rather depends on what you are doing with the finished product as to whether you can use such systems (that's the 'no' bit  ).
While we're at it, if you check the archives, you will find that there's a bit of a question mark hanging over the 80min CD. Again, because they are 'non-standard', there are some domestic (and professional) CD players which have problems when trying to play these discs.
... and another thing. Since you are transferring cassettes, you must ensure the azimuth of the replay head has been set to optimum, relative to the tape being played. Again, you'll find a lot of discussion about this in the archives and it really is a most important point where cassettes are concerned.

Thanks for the info--I'll stop my search for speed but will still need to perfect size---- the quality is not much of a factor as 23yrs of flying helicopters has "slightly degraded" the fine receptors in my hearing. I will not be using any tapes for music just "audio books on tape"--- I have many and when I drive it keeps me awake-- my vehicles only have cd and the portable tapes arent real pratical---- If I can get 1 90 min tape "conpressed" on 1 cdr, quality will probably be better than my receivers--thanks much

That's the problem I outlined in my last post. It's not just a quality issue, but a practical one as well. I'm sure there must be some around, but I'd lay better than evens that your vehicle players will only understand a normal CD, not anything like MP3 or other compressed format files.
Unless you are prepared to change the player/s then you are stuck with using two discs per tape - I see no other practical solution.

Hi Graeme, I just wanted to point out that you might be confusing the
RAR compression technique with RealAudio. Winzip will unzip a rar file with the proper plugin.
However, this is all academic since the link simply leads to a page that says: f*** Da Leeches!
Very classy! :???:

Yes - you're right. I just didn't read the file extension properly and leapt to the conclusion it was a Real Audio file. Silly thing is, I have Winrar installed here.
