Thomas Harte	58be770eaa	Factors out some boilerplate. ... When I'm confident this is correct, I can fix up the other call sites.	2021-03-21 00:14:48 -04:00
Thomas Harte	267006782f	Starts to add Qt target; resolves many build warnings.	2020-05-30 00:37:06 -04:00
Thomas Harte	eed357abb4	Introduces concept of 'average peak volume' in order better to normalise audio sources like the OPLL.	2020-05-09 17:57:21 -04:00
Thomas Harte	9835e800ec	Fixed: individual audio generators now either are or are not stereo. The speaker acts accordingly.	2020-02-16 18:28:03 -05:00
Thomas Harte	89d6b85b83	Adds optional stereo output for the AY. ... The real chip provides the three tone channels as separate outputs, so a variety of different mixings can exist.	2020-02-15 18:09:17 -05:00
Thomas Harte	206ab380c7	Introduces double-resolution envelopes for the Atari ST.	2019-12-18 22:03:02 -05:00

Thomas Harte	1a9cea050e	Minor: ensure AY registers *read* as 0 from reset, as well as being 0.	2018-06-01 19:48:42 -04:00
Thomas Harte	0b771ce61a	Removes all instances of the copyright symbol.	2018-05-13 15:19:52 -04:00
Thomas Harte	48737a32a7	Introduces formal setting of the output volume to SampleSource. ... Previously every output device was making its own decision. Which is increasingly less sustainable due to the CompoundSource.	2018-03-09 13:23:18 -05:00
Thomas Harte	3c5a8d9ff3	Adds Super Game Module support for the ColecoVision.	2018-03-03 13:08:33 -05:00
Thomas Harte	2dc1d4443e	Separates LowpassFilter and SampleSource.	2017-12-18 21:39:23 -05:00
Thomas Harte	ac80d10cd8	Separates the component parts of running an audio stream: task deferral, filtering and generation. ... Walking towards improving opportunities for composition.	2017-12-17 21:26:06 -05:00
Thomas Harte	5b6ea35d96	Corrects initialisation ordering for the ZX80/81, C1540 and AY-3-8910.	2017-11-10 22:31:27 -05:00
Thomas Harte	f95515ae81	Eliminates a large number of instance of end-of-line tabs.	2017-11-07 22:51:06 -05:00
Thomas Harte	82367a2246	Added documentation.	2017-08-16 09:14:56 -04:00
Thomas Harte	3947347d88	Introduces active input handling for the AY and uses it in the CPC to give proper, active keyboard input, rather than push-on-select, which was only ever a temporary hack. Also maps a few more keys for the Amstrad.	2017-08-15 22:47:17 -04:00
Thomas Harte	745afd217f	The port input/output flags are now honoured; reading a port that is set as an output returns the current output value.	2017-08-07 19:01:18 -04:00
Thomas Harte	3ca9c38777	Attempted to move to more accurate bus reading — if control lines are set then all subsequent data inputs should act according to the current control lines; changes to port input should be reflected live upon readings, etc.	2017-08-02 19:45:58 -04:00
Thomas Harte	0267bc237f	Added the ability to set a port input, and relaxed bus state testing. I think my on-demand bus reactions here are inappropriate, so more work to do here probably.	2017-08-01 18:04:51 -04:00
Thomas Harte	e6854ff8db	Corrected typo: the input to an AY is BDIR, not BCDIR.	2017-08-01 17:06:57 -04:00
Thomas Harte	2d4e202be3	Completed dangling comment.	2017-08-01 17:01:36 -04:00
Thomas Harte	36bc558798	Converted all 'Components' to postfix underscores.	2016-12-03 10:51:09 -05:00
Thomas Harte	fd823dc222	Settled on terminology.	2016-10-23 20:42:49 -04:00
Thomas Harte	b12f2f2796	Switched to more straightforward version of two-step loop, dealing with my mistaken dealing of when _master_divider&15 == 0 upon entry without adding an extra sanity check. Am also temporarily on non-modulo logic for tone generation, for a profiling test.	2016-10-23 20:32:48 -04:00
Thomas Harte	583db88299	Added a dispatch queue-powered Apple implementation of the async task queue, removed any mention of skip_samples in the AY since it isn't implemented.	2016-10-22 21:58:45 -04:00
Thomas Harte	33e628a096	Made an attempt to eliminate what amounts to manual division.	2016-10-21 22:16:44 -04:00
Thomas Harte	782ef960e1	Sought both to [start to] optimise the AY and correct divider reloads. It turns out that conditionals aren't that troubling. But I can probably eliminate the counters.	2016-10-21 20:05:38 -04:00
Thomas Harte	cd59eb5f43	Implemented non-linear volume.	2016-10-19 23:07:51 -04:00
Thomas Harte	b59da7d4bc	Added some documentation.	2016-10-19 22:47:44 -04:00
Thomas Harte	6073906c39	Commented and fixed mistake that would equate any noise divider > 32768 with 0.	2016-10-19 21:51:35 -04:00
Thomas Harte	ada37abe23	Made an attempt to implement noise and envelopes. Not quite right yet.	2016-10-19 21:13:22 -04:00
Thomas Harte	9669a5ec9b	Switched to a more authentic interfacing to the AY.	2016-10-18 19:32:15 -04:00
Thomas Harte	43612e1ca2	Made an attempt to eliminate conditionals (running before I can walk?) and started edging towards an envelope generator.	2016-10-17 08:03:38 -04:00
Thomas Harte	9730e8247f	Ensured propagation of synchronise messages, added enough to do plain tone. Probably. So: noise and envelopes missing. And it's all far too quiet.	2016-10-15 21:04:21 -04:00
Thomas Harte	51bdac27ae	Made some AY advances; it's now being polled for samples and collecting more information on what it needs to output.	2016-10-15 17:45:39 -04:00
Thomas Harte	288d10c253	Got some keyboard reaction.	2016-10-14 21:44:15 -04:00
Thomas Harte	d8e4c488c2	Started iterating towards having an AY and a fully-working keyboard.	2016-10-14 21:18:03 -04:00
