Slow down the CD and keep the same pitch

What is the name of the electronic device that does this:
Play the CD at a slower tempo and keep the same pitch.
I’m not interested in getting a software program. I’m searching for a portable electronic thing like a CD player. I think this was advertised in the Suzuki Journal last year. How do I look through past advertisements? Thanks!

if Tascam isn’t what you want (Google it), try, Superscope (which was advertised some years back in the SAA Journal).

I believe these devices are also designed to take out the vocals (or “lead” instrument) if you need it; they can also change the pitch without changing the speed; some of them allow you to plug a mic in—basically acting like a karaoke machine—and some models can burn you a new cd while you’re at it.

A little too high priced for me the last time I checked.

There is a free software solution to this, if you don’t mind doing a little bit of work.

CDex (search for it on Google) is a free audio extraction software that you can use to pull the tracks off of the CD onto your computer in uncompressed waveform format. From there, use the program Audacity (also free, to open up the file. There are effects to change pitch without changing speed, change speed without changing pitch, and others that can accomplish what you need.

At this point, you can then put the slowed down version, plus the original onto an iPod or similar portable listening device…something small that can be kept in the instrument case. :)

p.s. Every SAA Journal should have an advertiser’s index at the back. However, you’ll need a copy of the journal with the ad you’re looking for, the indexes aren’t posted online. And you’ll need to know the name of the “parent” company (if there is one) for the product you saw advertised.

Another approach: Purchase the MIDI accompaniment CD (through Shar or any other dealer) for the book you need.

Load this into your computer. Standard MIDI files can be played several ways. QUICKTIME can be downloaded from the internet for free. Using Quicktime, you can change the tempo OR the key or both.

Of course, you are going to get only the piano part (no violin part).

Perhaps the original poster can describe why slowing down is desired. Is it to perform? Is it to hear details or fast passages to aid the initial learning of the piece?

Thanks for your postings. Tascam does make what I’m looking for. I want to slow down the CD to transcribe what the fiddlers are doing in fiddle bands.
