AIFF to Wave Converter – Open an AIFF file in the program, and it will convert. Now you can easily open your Mac files and export them back to the original format. Filter Sweeper is a new filter that allows users to adjust the amount of notch, high, and low pass filters they apply over time. This filter is ideal for situations when more filtering is required at the file’s beginning. Sample Rate Conversion – Quickly convert files from one common bit depth and sample rate to another.

Many federal, state, and local government agencies use it for forensics law enforcement applications. This is especially useful in surveillance situations. This program is ideal for anyone involved in sound analysis and forensic research. Signal Triggered Voice Over Recording – This allows you to trigger the software to record automatically when a specified level of signal is sustained over a set period of time. Spectral filter – This filter can be used to create a high-resolution frequency response curve using up to 32,000 bands equalization using FFT techniques. Because of its steep slope characteristic and high-frequency selectivity, it is very useful in Forensic audio applications to remove out-of-band noises. The time-domain adaptive filter has been improved – This filter’s stability is significantly better and the Normalized version is much faster, especially at large filter sizes. Diamond-Cut Forensics Audio Laboratory has all these features and is an excellent software tool for audio study in forensic medicine.
For an easier transcription of long surveillance files, use the auto “Remove Silence” function. Windows WDM and MME Support – Will work with virtually any sound card. Many new factories preset are available – This is a great place to start. Spectral Subtraction Filter In Continuous Noise – A new and amazing feature of the Continuous Noise filter.
The AFDF, unlike other filters in the DC-Art series, is optimized for Forensics recordings. It does not support “High Fidelity”, files. It was designed to have a quicker response time, a smaller effective bandwidth, and produce higher levels of noise reduction. However, this could lead to higher levels of digital artifacts. The applications included recordings that were collected by law enforcement officers and other people responsible for removing bad evidence quickly in order to present it at trial. The Live/Forensic edition also saw improvements in forensics work. These included dual logging of the incoming unprocessed and outgoing processed audio streams, and a time and frequency domain adaptive filter algorithm for separating human voice from significant background noise.
Audio Mentor is a unique tool that guides users through an array of steps, including setting the recording levels, noise reduction, and sound enhancement, to creating a CD in just minutes. The program could automatically divide a file into individual tracks, such as when it was transcribed from an LP or cassette recorder. DC-Audio Mentor was released in July 2006 after several months of beta testing.
DC-6 may also have been the first to offer an “Auto-continuous Noise” FFT algorithm. This algorithm would automatically calculate the noise fingerprint for a recording and then update it on a regular basis. Although this method wasn’t as efficient at removing noise as traditional methods, it was more convenient for novice users or those with limited time and the ability to adapt to changing environments. Audio Mentor, as the name implies, was created to guide novice users through the restoration process.
These filters included simplified EZ DeClick, EZ DeCrackle, and EZ DeCrackle filters that can be used to repair unwanted impulse noises. A weighting function was also added to the median filter. This had the potential of de-crackling audio recordings and aiding speech clarification by changing the “timbre” of sound, which is often required for forensic audio recordings. A de-clipping filter was also added. The multifilter can perform a record restoration quickly on the fly, which is often required for radio broadcasting. Other improvements include VOX recording capabilities, timer recording, and dithering. The functionality of the continuous-noise filter was also modified. New inflection points were added to match the FFT filter curve with the sampled noise to make it easier to remove without creating digital artifacts. DC-Art 32, also known as DC-Art Version 3.0, was released in 1998.
The “Sub-Harmonic Synthesizer”, and “Overtone Synthesizer” were two of the most innovative additions. These filters produce harmonic frequencies that re-create the lower and higher octaves lost in a recording, improving restoration’s fidelity. DC-8 is Diamond Cut Audio Restoration Software’s latest release. DC8 was released in private beta testing in late November 2009. Due to significant changes made to the program’s core, beta testing was delayed for several months. The final release date was March 2010. DC8 featured a variety of innovative and novel advances, including a “Big Click Filter”, which automatically repairs large clicks caused by cracked or badly gouged records.
Diamond-Cut Audio Restoration Tools (DCArt) was initially a private enterprise by Craig Maier, an R&D engineer, and Rick Carlson. The original concept of DC-Art was developed in the early 1990s to preserve the Edison Lateral collection, which includes test pressing recordings, at the Edison National Historic Site, West Orange, New Jersey. DC-Art was created to allow test pressings to be transferred to digital tape in order for preservation and archival reasons. Over 1200 songs were recorded using the original software. This included many recordings that hadn’t been played since the 1920s. This innovative tool can remove distortion from audio files. Drag and Drop File Support: Drag and drop any audio files supported by the program, and it will open and convert them automatically.
Audio Laboratory 10: Research and audio analysis in Forensic Medicine is one of the most challenging tasks. This requires sophisticated software that integrates scientific terminology and knowledge. Subsonic Explorer This tool provides an operator with a clear indication at 30Hz and lower and allows him or her to correlate it to the time domain waveform. This is especially useful for authenticity studies that require analog edits. You can use the lowpass, highpass, and bandpass filters to detect sharp edges. A spectrogram viewer that shows frequency versus time is also available. Also, you have a de clipper to remove clips from files that are distorted. You can edit the Wave header to change the format tag, sample rate, and number of channels. Bit depth, block alignment, and average bytes/second are all possible.
This gives you a fresh perspective on your audio and provides some interesting insights.
DC8 introduced the Direct Spectral Editor tool, which allows users to manually attenuate and interpolate long-lived noises on recordings, such as coughs, whistlings, chair movement, or other spurious signals. The spectral editing tool can also be used to remove unwanted “swoosh”, sounds from audio recordings that otherwise would not be possible without significant audio quality degradation. Although the DSE tool was discontinued in the United States, it is still available worldwide. Other improvements were made to make it easier for novice users and reduce the time needed to restore recordings from old shellac records.
