Most of us have heard of digital compression, but what does it really mean? And why is Sound Therapy so much better?
Digital Compression
Digital compression is mainly performed in the frequency domain. In compressed sound a few samples of the sound are taken but a large percentage of data, up to 90%, can be discarded. For the average listener the sound can still be recognized without this complex data. The result is a smooth wave form, from which many frequencies, especially the higher frequencies, are missing. This is the core of digital compression.
A single wave form smoothed out by compression is illustrated below. This is an illustration of typical MP3 sound.

In addition to frequency compression, sound is also compressed in time, so that fewer samples are played back each second. Here is an illustration of sound waves over a period of time.

After both the frequency and time domain compression processes, the spectrum datum are simplified as illustrated below. (Note: The illustration is overly simplified for easier understanding.) Thus, a huge amount of information is removed and permanently lost. (This is the reason why this type of compression is called “Lossy” Compression.) Moreover, MP3 often uses a lower sampling rate than a CD, which creates a total loss of information above a particular frequency (that being 1/2 of the sampling frequency). Note the sudden information loss over the specific frequency in the illustration.

The sound reproduced from this data file sounds okay to the average listener. A piano still sounds like a piano and a trumpet sounds like a trumpet, but the details, nuance, and musicality are lost. The sound becomes rather dull, and is largely devoid of any therapeutic benefit.
What’s Wrong with MP3?
MP3 data contains a minimum amount of information attempting to reproduce the sound in an acceptable quality. A mere 1/20 of the original information is kept and the rest is permanently discarded. (Instead, you can store 20 times more music in the same media.) The narrowed frequency range is another tactic to compress the file size. It is noticeable that the MP3 music obviously has less high-frequency information compared to CD music. This is a common problem to any digitally compressed audio including WMA.
In contrast, the technology used in Sound Therapy recordings both replicates and enhances the original harmonics and frequencies in the music, using a combination of therapeutic filtering systems and state of the art digital playback technology.
A new enhancement for Sound Therapy
Our new playback system for Sound Therapy being launched this week is a beautifully engineered miniature player called the MINI MX2. The MINI MX2 uses two specialized processes to ensure accurate and harmonic rich playback.
MP Process
The MP (Minimized Polynomial Non-Linear Saturation) Process effectively generates harmonics indicated as “ Generated Harmonics by MP Process ” from a “ Fundamental ” note in the illustration below. The even order harmonics create harmonized, warm and comfortable sound, while the right amount of odd order harmonics makes the sound brighter and sharper, when they are added to the original sound. The result is a warm and comfortable, yet distinguished sound.

BBE MP Process
BBE Sound is a premier audio technology process used to improve the quality of amplified sound for those seeking a superior listening experience. BBE High Definition Sound technologies are a cutting edge advancement in digital sound delivery now in demand by world-renowned musicians and top sound engineers.
Sound Therapy International is now implementing BBE High Definition Sound technologies into our products so that they provide a more satisfying and therapeutic audio experience for our listeners.
The BBE Process, which provides a linear phase advance in proportion to the frequency, is placed before the MP process. The MP process evenly generates higher harmonics from the entire audio bandwidth. Since the BBE-processed sound has a tapered time alignment (the higher the frequency, the more time advance), the generated harmonics are time-advanced in the higher frequencies. This allows the brain to analyze the sound more easily with the least amount of added harmonics. (It is common knowledge in the psycho-acoustic studies that time-advanced harmonics, compared to fundamentals, make the brain’s interpretation of sound easier.)

The BBE process progressively enhances the higher frequencies. The harmonics generated by the MP process tends to have more elements in the higher frequencies compared to the lower frequencies. The degree of this contrast is optimized by the BBE process gain.
The BBE MP process ensures optimum rendition of the complex fluctuating high frequency-rich Sound Therapy retaining its complex variations with absolute detail, clarity and sharpness, for ultimate neural stimulation and brain recharge. Sound Therapy has never sounded better!
