Spectron performs a significant number of calculations when
running. Although it's been highly optimized for current CPUs, here are some
tips for using it effectively even on lower speed machines:
1) If you're not using modules for processing, you should be sure to bypass them to conserve CPU power.
2) You can use less bands for processing. In the main Options screen, try using 256 or 512 bands instead of 1024 or 2048.
3) Try changing the buffer size and/or latency setting in your host application. When buffers are too high (latencies are too large), meters will update very slowly and performance may suffer. As buffers become very small (latencies are very low), the Spectron Engine will consume more CPU. See Buffer Sizes for details.
4) You can disable meters in their option screens. Right click on any meter to bring up the options screen for that meter.
5) You can force Spectron to process stereo files in mono, requiring almost half the CPU for half the channels. This is useful while previewing to save CPU in some cases. You can enable this option in the General Options tab .
