Unlike computer-based sofware system, these operate in real time. You do not have to record onto a computer, then process, and finally listen to or burn a CD. This noise reduction units can be adjusted and used as you listen and they operate in two steps. They can be easily integrated into an ordinary hifi system, or professional system via RCA input and output jacks. A complete system would consist of a Surface Noise Reducer connected in series to a DEHISSER. One may also purchase either unit if only one form of noise was found more annoying. For 78 rpm reproduction, the DEHISSER probably provides the most benefit. For LP listening, the Surface Noise reducer may provide the most benefit. With older records, you can obtain optimum noise reduction by combining the Surface Noise Reducer and the Rek-O-Kut Dehisser into a system.
In evaluating these systems, it is necessary to consider the psychoacoustic factor. When listening to recordings with high frequency noise, we also perceive more highs than are actually present. We tend to associate the two. When the noise is removed, we perceive that the highs are also removed.
A complete audio restoration system consisting of the Re-Equalizer, Surface Noise Reducer, and DEHISSER would provide the majority of features of the, now discontinued, Packburn Noise Reducer. That unit sold for $2,600.00 in 1988. The cost of our system costs exactly half of that and has better performance plus much less audio distortion.
EVALUATION CD. We now have available two CDs that demonstrates the performance of the noise reduction devices we sell. One CD demonstrates the performance of the Esoteric Sound Surface Noise Reducer, and another that demonstrates the performance of the Rek-O-Kut DEHISSER. Both also show the effectiveness of CEDAR products. Each is available for $3.00 ppd. This can be deducted from the purchase price of any unit you purchase. For more information:

REK-O-KUT® DE-HISSER
WHAT THE "AUDIOPHILE" MAGAZINES IGNORE:
"I am VERY VERY pleased...highly suggesting these...( De-Hisser and Surface Noise Reducer)… for anyone that plays and
collects 78,s and radio transcriptions"
"...how pleased I am with the results I'm getting with the
De-Hisser...It's the perfect solution for cleaning up the early music cassette
tape recordings that I'm working on"
"WOW !
- I've been having fun for the past few days...really impressive results on
some Louis Jordan and Rosetta Tharpe Decca 78's"
"...your groove wall selector...has bailed me out many times. You did a superb job of making that feature available"
"It is really nice to enjoy those early sounds ...without any kind of “overfiltering” or digital artifacts!"
"I am particular impressed by the clean sound from the Rek-O-Kut De-Hisser for playback of 78’s!
"I...was amazed at how the (De-Hisser) filter made the highs pop out rather than killing them off"
"Listening to you demos, we actually prefer the SNR + De-Hisser result over CEDAR"
"The combination of the ROK’s RE-EQ and dehisser together...is just dynamite!"
"in extreme cases I...play only one side of the groove (thanks to your de-hisser)"
"Selecting one groove wall plus the 80 Hz filter makes a huge difference"
"The Dehisser works well with my 78's. I'm very satisfied with it"
"I already use the Dehisser for a while now and it's fantastic!"
"I am really happy with the features and build quality!"
"The DeHisser works beautifully...I love it!"
"the dehisser... seems to fit the bill"
"What a difference"
Denoise Any Record Or Tape REMOVES THE NOISE, NOT THE MUSIC! While You Listen - No Computers
THREE
NOISE REDUCTION SYSTEMS IN ONE
for use with modern stereo LP records, old mono LP records, all tape/wire recordings, and vintage
noisy 78s
A perfect companion to follow the SURFACE NOISE
REDUCER
Easily connects to most hifi systems
The Rek-O-Kut De-Hisser is actually three products in one: a background hiss
reducer, a left/right groove wall selector for mono records, and a low frequency noise
rumble filter. Use it in real time. No time wasted with computers.
Great for motion picture work. With zero latency, no loss of
voice synch. Installation is most convenient thru the external tape
monitor circuit or your preamplifier/receiver. If none, we suggest
getting one of our phono preamps, connecting to your amplifier's AUX input. A furniture-grade
walnut case is available, look under
ACCESSORIES. Not supplied with
interconnect cables. Send for
our 44-track demo CD.
Please include $3.00 for postage.
GROOVE WALL SELECTOR, a must for collectors or restorers of mono records. This switch permits you to select the least noisy groove wall of a mono record. In addition, the Rek-O-Kut De-Hisser features a unique circuit which cancels out rumble and similar noises that are common to both groove walls. Other switching circuits (left only or right only) permit low frequency noises (rumble) to be heard unimpeded. Our added circuitry removes the rumble and not the bass. For more details, click here.
HISS REMOVAL is not accomplished by a common variable, and in most cases manual, hi-cut circuit. These 1940's technology filters remove either the music or cause an annoying pumping sound of the background noise. The DE-HISSER uses several automatic, music-controlled filters within the spectrum of the program material. Thus, you do not notice it do anything, but make the music much more noise-free. Background hiss is one of the most annoying noises produced by tapes, cassettes, and records from 78 rpm thru vintage mono LPs to more modern stereo LPs. Using analogue filtering, it introduces absolutely no CEL telephone-like sounds commonly obtained with digital techniques and computer programs. Gain 10 dB of Signal to Noise Ratio.
THE LO-CUT Subtly removes low frequency noises that can muddy the sound of records all vintages. This switch can select two amounts of low frequency noise attenuation. The 40 Hz position will suffice for many noise-plagued LP records and 78s, while the 80 Hz position may prove useful with old acoustic records, records with, rumble, severe warps, or records requiring bass boost.

ESOTERIC SOUND SURFACE NOISE REDUCER
Effective On Most Ticks, Pops, And Some Crackle
THE
ANALOGUE SOLUTION
"That
SNR is awesome!"
"It is a great product for my LP collection...and it works"
"Much lower overall surface noise, greater clarity and body to the music"
"an unlistenable record...is now very enjoyable to listen to straight through. Thank you"
"Superb instrument! ...a new record with some ‘factory’ pops, totally gone...a badly beat up ‘45...cut out about half of the most annoying pops"
"it's really impressive when ...between LP bands, ...When these surface noises are moderate, they are substantially reduced, and when...low, ...disappear"
- eliminates
or reduces these noises from most types of phonograph
records. Its circuit
can identify and remove many clicks and pops
found on Lp's and even 78's and other vintage records.
It will cause
minimum degradation to either audiophile or vintage records and is
suitable for inclusion into advanced audiophile systems where phonograph
records are used. While use
of a graphic equalizer or "scratch filter" to remove ticks and
scratches is somewhat effective, such filters reduce or eliminate the
highs found on records. The
Esoteric Surface Noise Reducer
acts only on the click or pop without effecting program material.
The Surface Noise Reducer
is also very effective in reducing ignition noise from FM radio
broadcasts.
It requires the input of a stereo signal, even if of mono material.
Mono disc records must be played with a stereo pickup.
Installation is most convenient thru a recorder/external equalizer monitor
of your preamplifier/receiver. If none, use a stereo preamplifier.
Connect its output to the SNR's input and the SNR's output to an AUX
input on your amplifier. Not
supplied with interconnect cables.

CEDAR Audio perfected audio restoration in the 1980s. CEDAR automatically noise prints thousands of time a minute. RESTORE is a combination of eight favorite restoration tools into a single package: CEDAR Studio Restore.
Record from your tape or disc source to digital, and do
the noise reduction later, and be able to change settings as your project
progresses. Insert CEDAR into a multitrack while
combining from various sources. This allows you to balance noise
levels if dealing with disparate sources.
Eliminate clicks easy
DECLICK offers better impulsive noise
detection than any other declicker. This performance is so good that, in
most cases, it's not possible to hear that the signal was damaged prior to
restoration.
Remove frying bacon &
crackle
DECRACKLE Removes all manner of ground-in and grungy crackle without damaging the wanted audio. It can also remove many forms of buzz and distortions from material ranging from cylinder recordings to studio lighting buzz.
Automatic dehissing that really works
AUTO DEHISS embodies an advanced algorithm that is far less susceptible to
the 'underwater sound' often found in other noise reduction software.
It automatically determines the noise content and removes it without
introducing unwanted artifacts. A manual mode is also offered for
fine-tuning the results.
Eliminate buzz and hum
DEBUZZ easily removes buzzes and hums with fundamentals as high as 500Hz,
and it can eliminate harmonic components across the entire audio spectrum.
It will track varying tones without unwanted side-effects such as the hollow
sound introduced by comb filters.
Reconstruct clipped audio
DECLIP 2 removes clipped samples and reconstructs the original signal,
improving clarity, distortion, and original dynamic range. teven
tracks the clipping amplitude so that already compressed material can still
be restored. Does wonders with "blasted" mics and grossly clipped
solos.
Control dynamics with a natural
sounding, unique
limiter
ADAPTIVE LIMITER constrains the peak level of the output while retaining the
integrity of the input, resulting in a more natural audio than processed
using other limiters. It is ideal for mixing, final mastering and other
creative duties
Remove extended clicks and scratches (Pro
Tools only)
MANUAL DELCLICK is ideal for restoring the extended scratches and clicks
encountered on film, tape or disk media. Its dual processes,
optimized for long clicks and scratches, will remove noises found on optical
soundtracks, as well as drop-outs and extended digital errors.
Removing bumps and thumps (Pro Tools only)
Dethump eliminates the thumps that
accompany many large clicks. It replaces the unwanted sound with
restored low frequency audio, and is the ideal tool for removing many noises
from optical soundtracks, cylinders, 78rpm discs, and even bumped stands.
