From 52e49500bb78974d43bdfd30b2ec9b2a4522dd25 Mon Sep 17 00:00:00 2001 From: David Robillard Date: Fri, 26 Feb 2010 01:39:16 +0000 Subject: Perform all mixing for an audio input in a single mix operation (instead of a two step polyphony mixdown (by connections) and connections mixdown (by ports)). Speed up and inline AudioBuffer::accumulate, to speed up mix(). Remove local buffer from Connection (always mix into destination InputPort's buffers). git-svn-id: http://svn.drobilla.net/lad/trunk/ingen@2494 a436a847-0d15-0410-975c-d299462d15a1 --- src/engine/PortImpl.hpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'src/engine/PortImpl.hpp') diff --git a/src/engine/PortImpl.hpp b/src/engine/PortImpl.hpp index 637336af..cb458d01 100644 --- a/src/engine/PortImpl.hpp +++ b/src/engine/PortImpl.hpp @@ -68,6 +68,8 @@ public: */ virtual bool prepare_poly(BufferFactory& bufs, uint32_t poly); + virtual void prepare_poly_buffers(BufferFactory& bufs); + /** Apply a new polyphony value. * * Audio thread. @@ -92,7 +94,7 @@ public: /** Empty buffer contents completely (ie silence) */ virtual void clear_buffers(); - virtual void get_buffers(BufferFactory& bufs, Raul::Array* buffers, uint32_t poly) = 0; + virtual bool get_buffers(BufferFactory& bufs, Raul::Array* buffers, uint32_t poly) = 0; void setup_buffers(BufferFactory& bufs, uint32_t poly) { get_buffers(bufs, _buffers, poly); -- cgit v1.2.1
