Roger Dannenberg ff60f598f3 Fixes 2 bugs in Nyquist: (1) Bug 2706 probably already has a workaround in place, but the original code called snd-samples with ny:all for the maximum length to retrieve, and now that ny:all is bigger than 32-bits, the value was getting truncated. This change fixes legacy code to be 64-bit-aware. (2) allows sounds to be accessed beyond their stop time even when they stop in the middle of a block of samples. For example, this Nyquist prompt no longer generates garbage or crashes: 
(setf idur 5000)
(setf impulse (extract-abs 0 (/ idur *sound-srate*) (cue *track*)))
(mult 0.01 (convolve *track* impulse))

  • High quality using 32-bit float audio processing.
  • Plug-ins Support for multiple audio plug-in formats, including VST, LV2, AU.
  • Macros for chaining commands and batch processing.
  • Scripting in Python, Perl, or any language that supports named pipes.
  • Nyquist Very powerful built-in scripting language that may also be used to create plug-ins.
  • Editing multi-track editing with sample accuracy and arbitrary sample rates.
  • Accessibility for VI users.
  • Analysis and visualization tools to analyze audio, or other signal data.

Getting Started
