What Are the Demo .wav Files?
(Test Audio Files)
Getting started demo1.wav This file is a raw transfer (with proper turnover EQ applied) of an Edison Electrical Lateral Cut Disc (thin-cut) test pressing recorded circa the late 1920s. It is just a snippet of a song called “My Sin” and can be found in its entire form and completely cleaned up on the Diamond Cut CD entitled “The California Ramblers - - - Edison Laterals 2”. This demo .wav file contains a large number of clicks and ticks (and some hiss too) and thus is primarily designed to be used to demonstrate the operation of the various impulse filters in your software. In particular, you will find a preset titled “demo1.wav de-clicker” within the EZ Impulse filter. This preset will de-click that file, but you can also use this demo file to experiment with the various parameters within that filter. It can also be used in conjunction with the EZ Clean and the Expert Impulse filters for experimentation purposes too.
RadioDemo.wav This file is a recording made on the East Coast of the USA of a German Broadcast as received on a short wave radio receiver at around noon time, EST. It contains a lot of hiss and the audio level varies a bit throughout. This .wav file is useful to show the multiple filtering/effect capability of the Diamond Cut Multifilter. To hear what it can do, just bring up the Multifilter and then bring up the preset called “Short Wave Radio Anti-fade & Cleanup”. You will see a lineup consisting of 5 filters and effects connected in cascade. Use the Preview button in the Multifilter to hear the result and use the bypass button to hear the unfiltered sound. Experimenting with the various filters and parameter settings contained within this preset in conjunction with this .wav file should prove instructive.
BigClickCracked78Demo.wav This .wav file is taken from an electrically recorded 78 RPM record which has a crack running from the outside rim all the way through to the center hole. It is a snippet of “The Blue Danube” and was recorded in the early 1950s. This demo file is intended to instruct you in the operation of the “Big Click” filter. Note that ratio settings of around 1.4 to 1.7 are effective and that the “thump” produced once per revolution of the record can be squelched by turning on the “De-Thump” feature. After the Big Clicks are repaired, use the EZ Impulse Filter to remove the remaining smaller clicks and ticks. The Preset in the Big Click Filter to repair this demo file is called “Big Click Cracked 78 Demo Repair”. There is a more thorough filter called “Big Click Cracked 78 Demo Repair (Comprehensive)” which not only eliminates the big clicks, but also the smaller crackle heard on this badly damaged record.
Aircheck 1933 Demo.wav This .wav file was recorded in 1933 on an RCA pre-grooved radio/phono/recorder combination located in Waukesha Wisconsin, 370 miles from the ‘clear-air’ 50 kW AM radio station KMOX from which it was live-broadcast from St. Louis, Missouri. It comes from a one of a kind record and is the first recording including a popular musician/inventor. We’ll let you guess who it is. There is a Multifilter preset that is all set up to clean this crude recording called “Aircheck Radio Recording 1933”. This is a good file to use to help you to become familiar with some of the tools found in the Diamond Cut Productions software, since the record suffers from a large number of audio defects.
Wind Noise Demo.mp3 This file is taken from a field recording of a jam session and contains wind noise mixed with musical content. Use this file to help you learn how to use the Wind Noise Filter. A preset has been set up for you to experiment with called “Wind Noise Filter Demo”. Although this file is musical in nature, the filter is actually optimized for spoken word recordings in very windy environments. The other presets found indicate the level of wind that this filter can be used on.
HissBurstDemo.wav This .wav file has a hiss burst roughly 8 seconds into it. The hiss burst was likely caused by the momentary loss of the RF carrier during an FM broadcast. This hiss burst is used to demonstrate the various functions associated with the Bi-Modal Interpolation (the “I” key) feature. You can highlight the hiss burst and experiment click on the I key, and it will be interpolated out of the piece. It’s as simple as that.
Vertical Cut Demo.wav This is a Pathe’ vertical cut acoustically mastered disc which permits you to experiment with the Virtual Phono Preamp (VPP) and it mono – vertical cut feature. The recording is called “Skies of Normandy”. The VPP will resolve this very noisy recording’s vertical component of displacement and only leave behind the true signal which is in the vertical undulation direction and rejecting most lateral direction influences. A preset is provided called “Vertical Cut Demo Preset” as a demonstration of what this filter can do to the vertical cut demo file.
Dyna-Bass Demo This is a song titled “True Blue Lou” performed by Catherine Annette Hanshaw, circa 1929 on the Diva record label. It is a lateral cut 78 having considerable amounts of rumble, but some deep bass buried with the musical performance. Use the “Dyna-Bass Demo” preset as a starting point to enhance the bass on this file while rejecting much of the rumble. Note that there are two other demo presets that you can experiment with in the Dyna-Bass preset listing.
dssdemo.wav This .wav file is a simulation of a loud bar room situation in which a male person is discussing a situation on the phone with loud rock music playing on the jukebox in the background. One side of this phone conversation is picked up by another nearby party in the bar via a “wire” that he or she is wearing. The recording is binaural in nature with one microphone located close to the jukebox and the second microphone hidden on a person and located in proximity to the person who is on the telephone. It is intended to demonstrate the usefulness of the DSS (Dynamic Spectral Subtraction) Forensics filter in terms of rejecting loud background music (or other types of coherent noises) from a surveillance recording. To hear this demo in action, bring up this file and then the DSS filter found in the Forensics menu. Then, bring up the DSS preset titled “dssdemo” or the preset titled “dssdemo-with gain”. To compare the results, switch the filter between normal “Preview” operation and “Bypass” mode. You may want to increase the “Output” control on the right side of the DSS to hear the conversation more clearly. An alternative preset to explore with the DSS filter is found in the Multifilter and is called “DSS Demo – Enhanced Performance”.
Note: The dssdemo.wav is only available in the DC Forensics version of the software.
Male Voice ID Test.wav This file uses a Broadcast Wave (BW) format for testing that software feature and can also be used to experiment with the spectrogram.
ForensicDemo.wavThis file is a snippet of an air-check recording of the famous inaugural speech made by F.D.R. in 1933 in which he stated that “We have nothing to fear but fear itself”. This recording was captured in real – time via an AM radio on a Victor Pre-Grooved Record recorder at that time. It was recorded from a radio transmission out of the New York metropolitan area via radio station WEAF and was received in Newark NJ via a combo Victor AM radio / disc record recorder machine. This file includes a combination of random and coherent noise signals (hiss and heterodyning) which are damaging to its intelligibility. Much of the noise that you hear is native to the original air-check recording. Other noises have been added in to demonstrate the de-noising capability of 8 filters/effects cascaded in the Multifilter. To evaluate this functionality after bringing up this file, go to the Multifilter and click on the preset titled “Forensic Demo Clean-up Filter”, and then Preview it. You will note that the voice is barely intelligible until you enable the preset. You can easily switch back and forth between the raw file and the enhanced version by using the “Bypass” checkbox in the Multifilter.
Note: This demo .wav file is only available in the DC Forensics version of the software.
Composite Bit rate mp3.wav This file is useful when experimenting with the Histogram vs. Time and the Comparative Histogram features. Suspicious edit points can be seen with this file.
Whisper Enhancer Demo.wav This file shows the power of the Whisper Enhancer feature found in the Forensics version of this software. The two demo presets are titled “Whisper Enhancer Demo Preset” and “Whisper Enhancer Demo Preset 2”. Their parameters are set differently so that you can observe those effects. Experiment around with the slider controls since you can always get back to the original factory demo settings. This demo file and filter/preset is only available in the Forensics version of the Diamond Cut Productions, Inc. software.
Voice ID / Voiceprint Demo Files: (Forensics versions only)Six sample .wav files are provided with the software to help you learn more about the voiceprint patterns of a female’s, male’s and child’s voice as recorded through high and low quality signal paths. These files consist of three persons saying the same “cue word” sentence. The low quality versions were recorded simultaneously with the high quality versions for ease of comparison using the Diamond Cut Spectrogram and Voice ID feature. Here are the files that are included:
Female Voice ID Test Sentence - High Quality.wav
Male Voice ID Test Sentence - High Quality.wav
Female Child (12) Voice ID - High Quality.wav
Female Voice ID Test Sentence - Low Quality.wav
Male Voice ID Test Sentence - Low Quality.wav
Female Child (12) - Low Quality.wav
The “Low Quality” files were recorded using a very low cost dynamic microphone manufactured circa 1970 and a commercial grade mixing board manufactured in the mid-1970s. The “High Quality” files were recorded with a studio grade large diaphragm condenser microphone in conjunction with a “dedicated” studio grade microphone pre-amplifier. All 4 of these files were digitized via a high-end soundcard. All of the files are sampled at 44.1 kHz with 16 bit depths.
Note 1: These demo .wav files are only available in the DC Forensics Audio Laboratory version of the software.
Note 2: The persons whose voices you hear on these demos were born, raised and live in Northern NJ, USA, in case you are trying to identify their accents.
Note 3: The Female Child’s voice is that of a 12 year old.
Forensics Files with Edits:
Microcassette Recording with Analog Edits.wav.
This file has analog edits made on a microcassette machine which can be detected using the Subsonic Explorer feature. The Subsonic Explorer is found via this path:
Forensics Menu/Authentication/Subsonic Explorer. The edit points will be seen in the destination display as impulse “spikes” where the edits were made. Just look above the Destination display at the Source file since the impulse spikes point to the edit points. There are no filter presets associated with this file.
Mary Had a Histogram (8 bit edit on 16 bit file).wav
Use this file to experiment with the Forensics Comparative Histogram and/or the Histogram (vs. time) feature. You will discover the edit point.
60 Hz Phase Shift with Phase 4 Discontinuity Final.mp3
This file will help you to experiment with the View Phase vs Time Forensics Feature found under the Forensics Menu. It includes varying phase as well as several edits. The phase discontinuities are graphically shown and clearly identified.
