Jun 08, 2008 Tools to fix wow & flutter from cassette ive got a cassette tape im working with & two tracks suffer from wow & flutter. Any software/tips/tricks out there that attempts to correct the issue?
We hope that this information will help others with selecting a cassette deck for audio preservation work.
Our Machine Selection Process
The Audio Archive considered many machines for cassette transfer, including the venerable Nakamichi Dragon, before finally standardizing on the Nakamichi CR-7A for preservation work.
The cassette format, also formally known as the 'Philips Compact Audio Cassette', is heading towards obsolescence. Fewer, if any, high quality cassette machines are still being manufactured. Many of the current machines on the market are of the 'dual well' design for duplicating cassettes and have features like 'auto reverse' which add mechanical complexity and imprecision.
Tune focus rs. With that said, our goals for cassette deck are:
- High quality playback of music and studio recordings
- High quality playback of spoken word and field recordings
- Long-term maintainability
The Nakamichi CR-7A cassette deck fit these requirements better than any of the many machines we considered and evaluated.
To serve the needs of music and studio recordings, the Nakamichi CR-7A outperforms any current production machine on a broad range of specifications from frequency response and distortion, to noise and separation. For example, the wow-and-flutter performance of the Nakamichi CR-7A (0.027%) is three times better than a current production machine like the Tascam 202 Mk IV (0.09%).
On the other hand, field recordings, and in particular spoken word recordings made in the field, have unique requirements. Typical cassette field recorders were subject to vibration and impacts when moved around, which in turn could affect the mechanical alignment of the recording heads. Furthermore, low-cost cassette recorders were often used in the field with poor or built-in microphones, delivering very limited frequency response, especially with spoken word recordings. To play back these recordings, the key requirement is manual playback azimuth adjustment to maximize frequency response. Altogether, only three Nakamichi machines were manufactured with manual playback azimuth adjustment:
Flutter And Wow Band
- Nakamichi CR-7A (1986-1993)
- Nakamichi Cassette Deck 1 (1990-1992)
- Nakamichi DR-1 (1992-)
Among the above three Nakamichi cassette decks, the CR-7A wow-and-flutter (0.027%) outperforms the Cassette Deck 1 and DR-1 (both 0.035%). Only the Nakamichi Dragon has superior wow-and-flutter (0.019%).
The Nakamichi Dragon has automatic azimuth correction (NAAC), which is a fantastic capability with music and high-quality studio recordings. However, the automatic azimuth correction relies on high frequency information to function properly, and field recordings may not have sufficiently high frequencies for the Nakamichi Dragon's NAAC to track. In this case, manual playback azimuth adjustment is the only possibility to correct for poorly aligned recording heads.
Electromechanical simplicity helps long-term maintenance of any precision machine. To that end, the Nakamichi CR-7A lacks mechanically complex 'convenience' features like auto-reverse or dual wells. Later production models of the Nakamichi CR-7A replace critical belts with a far more reliable gear drive. The Nakamichi CR-7A shares key parts like playback heads with other Nakamichi models, which makes sourcing of spare parts just a little easier.
Nakamichi CR-7A Brochure
What follows is all of the unedited text (including hyperbole and typos), all the technical details, and most of the pictures taken from an original Nakamichi CR-7A/CR-5A brochure. The Nakamichi CR-7A and CR-5A differ in that the CR-7A adds the following features:
- Auto Calibration
- Playback Head Azimuth Fine Tuning Control (manual)
- Real Time Tape Counter
- Auto Fade
- Subsonic Filter (for recording warped discs)
- Wireless Remote Control (controls REC/PLAY and Azimuth)
which are unavailable on the CR-5A.
Nakamichi, like Studer, were engineers at heart and their marketing brochures truly read like tech briefs or 'theory of operation' documents more than product brochures. In this brochure you will learn about sources of calibration error, azimuth alignment, cassette transport design, flutter, and more. The highlight color is used to emphasize important points in the original text. If the highlight is preceeded by the text 'The Audio Archive:', this indicates a comment by The Audio Archive, and is not part of the original brochure text.
If you don’t want any natural reverb, use shorter release times and either add some of the built-in reverb or use a third-party reverb plugin to process the signal. The plugin features four full octaves of clap sounds which I’ve recorded in different locations, with varying amounts of natural reverb that was captured while recording.You can use the simple global AR volume envelope to control the softness and the tail of the claps. Vst crack websites. There is some kind of 7Zip ad on the page in green with a big DOWNLOAD bar, so I had originally clicked on that. January 19, 2015 at 2:23 amSorry – my bad.
I am beginning to digitize some old cassette tapes but have run into a problem: many of the cassettes have significant speed/pitch variations on playback. I can't figure out if the problem is the tapes or the tape deck (or both).Background: I am beginning to digitize about 30 cassette tapes that contain music from bands that I was in. These tapes are from the late 1980s-mid 1990s, as is the Technics dual cassette tape deck that I am using for playback. The tapes are in good condition, having sat unplayed in a shoebox in the basement since the mid-90s, as is the tape deck, which has also sat unused in a basement since the mid-90s.
The problem: during playback, many of the tapes experience serious speed/pitch variation, and a 'crinkly' noise, primarily at the beginning of the tapes. I have tried lightly cleaning the tapes, and rewinding them all the way several times, but this doesn't seem to help.
My problem is that I can't tell whether the problem is in the old tapes or the old tape deck's old motor, either of which could be the culprit. I don't have access to any other tape decks to test the tapes (that's right: no one I know has a tape deck). These tapes have significant sentimental value, so I'm willing to buy a new tape deck if necessary, but would rather not spend the money for a one-time project if I can avoid it. What should I do?
If the tape ever unspooled, and had to be manually rewound you may get drop-out or crackles due to actual wrinkles in the tape.
Also, tape will get brittle with age.

If this were my project, I'd take a Q-tip and dip it in rubbing alcohol, and give a gentle rub to the heads and any other parts of the cassette deck that seem dusty. The advice on this page adds that you should 'NOT TOUCH THE SURFACE OF THE HEADS WITH ANY METAL OBJECT,' which seems reasonable.
Once you've cleaned with isopropyl alcohol, that's about all you can do with the cassette deck. I suspect, given the age of the cassettes (serious degradation begins around the ten-year mark) and the environment in which they were stored, that the issue is more the cassettes than the player.
(Again, if this were my project,) I'd buy a new tape deck. I would also avoid messing with the tapes for any reason whatsoever.* Cleaning the tapes will only harm them, as will rewinding--if you must rewind, gently twirl a pencil through the tape reels. It is likely that some/all of these tapes have only a few plays left in them, and you probably want that play to be preserved digitally. I'd tread lightly.
*although, if the tape does break off, it's worth a try to reconnect the ends with a gentle adhesive.

Might be worth seeing if there's a library or a university A/V department near you that has equipment you could try. Alternatively, cassette decks are pretty cheap on eBay.

Compare the playback on each one. If the problem clears up, it's the motor/belt on your old cassette deck. If there's still trouble, try to compare the patterns in the speedup & slowdown. Is there a slowdown *exactly* at a certain instant in a song? If that's the case the tape is likely deteriorated or the original recording deck way back when had a bad motor or drive belt. If there is no correlation and it's behaving randomly between the two decks, I'd dismantle and repackage the tape in a new cassette, as I've run into a few tapes that have tight tolerance or foreign contamination and that can add resistance to the tape transport.
In any case I would also test the tape sprockets and try winding it awhile and try to feel for any resistance. If there is, repackage the tape.
Regardless, if you can't fix the issue, I would digitize the tape anyway. Cyclic distortion from drive belt problems is theoretically salvageable since the time distortion in many cases (except for random slippage) has a predictable, wavelike pattern. I don't know if there are any software programs or Audacity plugins that deal with this, but if there aren't I wouldn't be surprised if something comes along sooner or later.

They can be expensive, but you can get them cheap on ebay, here's one for $15.
It's also important to know how to use it right and what dangers it poses - get this thing too close to tapes and other magnetic media when it's on, and it can ruin them. Take the cassette player unit to place by itself - give yourself about about a 10' perimeter from other electronic stuff and magnetic media, turn on the device when it's about an inch from the heads, and wave in in small circles around the heads and the capstans for about 5 seconds and begin moving the demagnetizer away from the heads slowly while still moving it in larger circles as you go - give it about 8 seconds to move the demagnetizer about 6 feet away from the player, then turn it off.
