Digital High-Definition

To store a sound digitally, the computer gets the value of air pressure
on the microphone membrane, thousands of times per seconds. This list of
values (samples) makes the digital sound, that can be stored, processed
by mathematical operations, or replayed by the reverse process.
Quality of a digital sound is therefore defined by two values:
- Its sample rate, which is the number of samples per second
- The sample "depth", in bits, which is the accuracy of each value, the number of different values each sample can take
The "Audio CD" quality is: 44100 Hz sample rate (44100 samples per second) in 16 bits, i.e. 2^16 = 65536 possible values.
Our products manage this quality without the Myriad HQ module.
With the Myriad HQ module, it's possible to use up to:
- 96000 Hz sample rate, more that the double, for a finer mesh, thus
better high-pitched sounds, a better sound dynamic, and a decrease of
noise ratio.
- 32 bits deep samples, 65000 times more accurate than an audio CD, to
avoid metallic tones (aliasing) and get a better accuracy in quite
sounds
These quality improvements can be applied to:
- The digital output, on which you listen to your score
- Uncompressed digital export (WAV) to process your audio data in another application
- Digital input from microphone or line in
- Digital tracks in your document, that can be mixed together of with regular music staves
Please be careful however, data in top quality are 4.35 times bigger than classic data
