ABOUT AUDIO ON COMPUTERS

Via an ASIO Driver

This is your best option if it is available. More and more audio cards designed

for serious music and audio use come with ASIO drivers.

As stated above, ASIO does not guarantee low latency, but it allows for it if

the audio card designers take advantage of its possibilities.

• Not all cards come with ASIO drivers. If in doubt check with the au-

dio card manufacturer.

• Using a card via an ASIO driver can give latency figures as low as

3ms.

• When you use ASIO, only one program at a time can access the

card.

✪ More information about ASIO can be found on Steinberg Media

Technologies’ web pages, www.steinberg.net.

Intel vs. Other Processors

When you run Reason under Windows, the clock speed of the processor is a

major factor determining how many devices you can use at the same time.

However, there are other factors that should be take into account, and one

important such factor is “floating point arithmetic performance”.

All audio operations in Reason are done with floating point calculations

(counting with decimal numbers rather than with non-decimal numbers, inte-

gers) to ensure the highest possible audio quality. You can get high audio

quality on an integer system too, but floating point is effective and accurate

when it is available.

Intel Pentium processors are fast at floating point mathematics. Some other

lower priced processor have taken shortcuts which reduce their performance

in this particular aspect. This will have noticeable effect on the performance

of the program. Our advice is:

✪ If you plan to buy a computer specifically for Reason, you can play

it safe and choose an Intel processor. Alternatively, make sure you

select a processor that is renowned for high floating point arith-

metic performance!

Macintosh Specific

Information

Under Mac OS there are two ways you can play back audio:

• Using the Sound Manager

• Using ASIO

What the Sound Manager does/is

The Sound Manager is a set of software routines in the MacOS. These rou-

tines take care of everything related to sound. If you are using the internal

audio on your Macintosh computer you are using the Sound Manager, it is

built into the system.

One specific character of the Sound Manager is its ability to mix audio from

several applications. This means that even when you run Reason, you can

run other Sound Manager compatible applications at the same time, and

they will all sound.

Mac Audio Cards that play back via the Sound Manager

There are a few rare Mac audio cards that play back via the Sound Manager.

! If you have an audio card for your Macintosh, we strongly recom-

mend you to try and find an ASIO driver for it instead of using a

Sound Manager driver. This will give you higher reliability and per-

formance.

Mac Audio Cards with an ASIO Driver

An audio card with an ASIO driver is your best option if it is available. ASIO

does not guarantee low latency, but it allows for it if the audio card designers

take advantage of its possibilities.

• Using a card via an ASIO driver can give latency figures as low as

3ms.

• When you use ASIO, only one program at a time can access the

card.

• Note that to use ASIO you need to add an ASIO driver file to the

ASIO Drivers folder in your Reason folder.

If several program take advantage of ASIO this means you will have to

duplicate this driver to each program’s ASIO Driver folder.

Technologies’ web pages, www.steinberg.net.
