AUDIO BASICS

About Sample Rates and

Resolutions

Sample rate and resolution are properties of digital audio, which determine

the quality of the sound. Generally, higher sample rate and resolution result

in better audio quality (but also larger audio files and higher demands on

computer performance and audio hardware). This table shows some com-

mon sample rate/resolution combinations:

To cater for all different situations, Reason supports multiple sample rates

and resolutions. This applies to the following areas:

Playing back

During playback, the audio resolution is determined by the audio hardware.

That is, if you have a 24-bit audio card, Reason will create audio in 24 bit res-

olution.

The playback sample rate can be specified in the Preferences-Audio dialog

(accessed from the Edit menu):

Note that the available options on this pop-up menu depend on which sam-

ple rates are supported by the audio hardware. Most standard sound cards

support 44.1 kHz and various lower sample rates, in which case you should

select 44.1 kHz for best audio quality.

Exporting audio

Reason can export audio, i.e. mix down the song or a section of the song as

an audio file (see page 86 for details). When you do this, you will be asked to

specify a resolution (16 or 24 bit) and sample rate (11–96 kHz) for the file.

✪ If you plan to open the exported file in another application, you

should select a format that is supported by the application. If you’re

uncertain, 16 bit/44.1 kHz is a safe bet.

Importing audio

When loading samples into the sampler or drum machine device, or ReCycle

files into the loop player, Reason supports files of a large number of sample

rates and resolutions. You can use files of different formats in the same de-

vice - one drum sound can be an 8-bit sample, the next a 16-bit sample, etc.

! Reason plays back all samples in 16-bit resolution, regardless of

their original resolution.

Comment:

22.05 kHz 8 bit Typically used in situations where small file

size is more important than audio quality,

such as games, some multimedia applica-

tions, sound files on the Internet, etc.

44.1 kHz 16 bit This is the format used on audio CDs (often

called “CD Quality audio”).

44.1 kHz –

96 kHz

24 bit These are formats used in professional stu-

dios and high-end recording equipment.
