Thanks in Advance for any help one of you might offer.


I am far from an Audio Pro, yet have been trying to take some old cassette tapes and restore the sound quality they originally had, and enhance it even. As for this file in particular it seems to have lost its high's and mids. When I run it through a simple EQ plugin I just dont get the clarity I need, it just sounds worse.


Here is the steps I took in recording this tape.

#1 - Used a brand new Sony Tape deck , with preamp mixer and got the sound quality as close to 0 DB as I could (as reccomended by many audio recording sites I have read). I recorded at 44.1 hz, 16 bit through my SBLIVE card. I saw no loss in quality from tape to digital.

#2 - I then loaded Wavlab and watched the spectrum analyser and saw the highs and some mids were very low. I tried to raise this up in value but it just made the sound even more distorted than it already was.


I have many tapes like this I would like to restore, re-master (or whatever the term is). I have attached this file (in original .wav format) and uploaded it to the alt.binaries.sound.mp3 newsgroup. The topic is called:

"Sound Pro's can you give tips on how to fix this Audio File? Email - Trick@lvcm.com"

You can also download the .wav file clip at - http://www.lvcm.com/trick/badwav/badwav.wav


Any help on cleanup (what software/settings to use), examples , web links on fixing this sorta of stuff is GREATLY appreciated!!!! Heck if someone wants to clean it up themselves and email it back with the steps you used to do it, that would even be better.

This advice would be Pricessless, thanks again in advance to anyone who can help this audio newbie.

Email - trick@lvcm.com


Thanks,

Trick


PS - I have read about the CEDAR system, is this hardware based only???

Hi Cupelix

PSS - Cedar is a company that does audio-restoration, you better have some really valuable tapes if you want to take it to them. Lets just say you don't phone them up with some Hendrix tape you found in the garage (unless of course it was one of those unreleased tapes!). You might get a bulk deal if you secure the loan from the bank :-)

Some thoughts on this

1) I had some tapes which I wanted to convert (can't live without that Platinum Blonde!) I found it easier to download them off some file-sharing places, it took awhile to find people who had a cd rip (and who did it well - no 96k XING rips) and replace some tapes that way. Its a lot easier to get a cd-rip then to mess around with restoring them (since you don't have the master tape you can't remaster the music), and considering that even on a brand new tape your S/N ratio will be less than that of a CD your fighting an uphill battle to get the original music.

2) Probably you have some tapes that you will not find online, for those you can encode and start trying to restore them. I guess it depends on how many nits you wish to pick but I can make a suggestion - the SBlive (from experience) is not a great encoder if you've got the extra cash you might want to invest in a real 96/24 bit card.

3) Depending on how dirty you want to get your hands in restoring the sound, they have programs from "easy" - 1 click to much more control like Wavlab or Sound Forge - I might suggest Steinberg Clean as a middle-ground solution, but I'm no expert - I recommend you get some more opions for this or do some more research.

Hope this gets you going
