15. Size may have an effect on latency and overall performance A smaller vector size may reduce the inherent delay between audio input and audio output because Pulsaret has to perform calculations for a smaller chunk of time On the other hand there is an additional computational burden each time Pulsaret prepares to calculate another vector the next chunk of audio so it is easier over all for the processor to compute a larger vector However there is another side to this story When Pulsaret calculates a vector of audio it does so in what is known as an interrupt If Pulsaret is running on your computer whatever you happen to be doing word processing for example is interrupted and an I O vector s worth of audio is calculated and played Then the computer returns to its normally scheduled program If the vector size is large enough the computer may get a bit behind and the audio output may start to click because the processing took longer than the computer expected Reducing the I O Vector Size may solve this problem or it may not On the other hand if you try to generate too many interrupts the computer will slow down trying to process them saving what you are doing and starting another task is hard work Therefore you ll typically find the smaller I O Vector Sizes consume a greater percentage of the computer s resources Optimizing the performance of any particular signal network when you are close to the limit of your CPU s capability is a tria

17. and Pulsaret is best when the I O vector size is on the order of 1ms We recommend setting the 10 vector size to 128 samples Having a setting of the latency separate from the I O vector size allows this to work without audio glitches on most hardware Using ReWire with Pulsaret The ad_rewire driver allows you to use Pulsaret as a ReWire Device where Pulsaret audio will be routed into a ReWire Mixer application such as Cubase Both Pulsaret and the mixer application must be running at the same time in order to take advantage of ReWire s services The mixer application should be also compatible with ReWire 2 or later for best results When the ad_rewire driver is selected audio from Pulsaret can be routed to any of 16 inter application ReWire channels which will appear as inputs in ReWire mixer host applications The first time ad_rewire is selected it will register itself with the ReWire system Subsequent launches of ReWire Mixer applications will then offer Pulsaret as a ReWire device For example after the Pulsaret ReWire Device is registered Cubase will have a Pulsaret menu item in the Devices menu When you choose it you will see a list of the audio outputs from Pulsaret They will default to the off state Click on any of the buttons to activate that channel Once the channel is activated it will show up in the Cubase Track Mixer Using ASIO on Windows Selecting an ASIO driver from the DSP Status window allows Pulsaret to talk directly to a
