Highest Time Stretching and Pitch Shifting Quality

CHRONOStream2 includes advanced time stretch and pitch shift abilities to acquire uncompromising high sound quality.

The software outperforms other traditional time and pitch scaling software in processing speed and sound quality, so that the software can be a worthy tool for professionals The CHRONOStream2 does not loose primary elements such as timings which voices come out and groove sounds of instrumental performances. Also, the technology keeps stereo phases stable, even after the original data are edited.

The technology has flexibility to handle any audio sources such as music, solo instrumental performances, songs, narrations and conversations.

User-friendly Interface

You can treat the whole feature on the main application window, so that every setting is simply specified and operated. Controllers, such as XY pad, drag-and-drop and others, are not only shown clearly, but also handled easily. New functions, Playback Range Specification and Rendering (Selected Range), have been featured.

Supports multiple formats

CHRONOStream loads mp3, wma formats as well as wav.

It streams audio files, so that long data can be treated properly.

The software arranges files in real time when they are played. The files are rendered into WAV files.

* The Windows Media Player 9 or newer is required.
* Licensed wma files are not able to be used.

Makes any sounds clearer

AlgorithmA new algorithm RHYTHM has been added to the Ver.2. When the RHYTHM switch is activated, beat-based audio materials, -drum loops and rhythm instrument sounds-, are processed not loosing their live beating tastes.

Other algorithms, -MIX and SOLO-, had already been featured in the initial version. They are appropriately worked for general mixed music sources, and solo instrument performances or peoples speeches, respectively.

With these three algorithms, CHRONOStream2 fairly handles every audio data to be high grade.

Controls human voice characteristics

Formant Control Pitch shifted human voices tend to be extremely shrilled or deep, so that they are not heard normally. The reason why it happens is because formants, which are elements to consist human voices, are shifted at the same time when sounds are pitch-shifted.

Formants mean peaks in frequency spectra. The peak points may be different upon vowels to speak and genders of speakers. When formants are shifted, the original sounds may be modified in totally different forms, so that they become another human voices, even worse, they are not human voices any more.

The new feature formant control avoids the problem. Specifying formant control values makes pitch shifted human voice data heard more naturally. Also, shift settings modify voice characters of speakers.

	Pitch or Formant
ALMA FLAMENCO Original	0
Normally pitch-shifted	+6
Pitch-shifted(with formant correction)	+6
Formant-shifted	+6

For Loop Sounds

"Groove Stretch"

Beat value modification and timing corrections allow you to create grooves, such as swing and shuffles, which are totally different from those of originals. And also, this feature makes swinging sounds stable.

"Groove Pitch"

Beat value specification and pitch changing settlement cover creation of a variety of sounds, such as scratches, bent pitches and special effects.

Above features help audio data to be changed into totally fresh sounds.

DX Compatible Plug-in, CHRONOStream2DX

Sample host:Sony the Sound Forge 8
*Sound Forge belongs to
Sony Media Software. CHRONOStream2DX, attached to CHRONOStream2, is the DirectX plug-in which performs on host applications for audio editing.

CHRONOStream2DX performs as same as the time/pitch scaling software CHRONOStream2 on host applications.

* For using it, a host application, which is DirectX compatible, is required.

* CHRONOStream2DX changes output/input sound lengths, so some host applications might not cope with it even they are DirectX plug-in compatible. Unavailable host applications are listed here.
