What is the difference between the 32-bit and the 64-bit version?

The 32-bit version is meant for older computers with less memory and/or a 32-bit Operating System.

The signal path is 32-bit for the 32-bit version, while the signal path is 64-bit for the 64-bit version, the latter being more precise but requiring twice the memory. Additionally, the 64-bit version makes use of the latest instruction sets (such as SSE) on the more modern CPUs to speed up processing tasks.

We endeavour to keep supporting older hardware for as long as practical.
