Been in Scotland for near 2 years already, working at RealtimeWorlds, more specifically in a game called APB<\/strong>.<\/div>\n
Times does fly when we’re having fun!<\/div>\n
Meanwhile, I did work a bit in czPlayer, but nothing really new. Mostly bugfixes or small features for a client.<\/div>\n
So despite not having any updates here in the blog, the following things happened to czPlayer<\/div>\n
– Some games using czPlayer were release<\/div>\n
– A client added iPhone support. Was as simple as creating a single class with about 160 lines of code.<\/div>\n
– Implemented volume ramping, which helps a great deal in removing clicks, especially for chiptunes<\/div>\n
– Added some other small features, again with minor effort. \ud83d\ude42<\/div>\n
– Fixed some bugs, especially related to Symbian.<\/div>\n
Also, apart from czPlayer, I managed to squeeze in some other small freelance work.<\/div>\n
The last few months I’ve been thinking where to go next with czPlayer, and I’ve decided to go with a new design.<\/div>\n
Personally, I think the current design is really good performance-wise, minimizing copying memory around unnecessary or other unnecessary overhead.<\/div>\n
For example, internally a Mixer<\/em> object contains MixerInputGroup<\/em> objects, and each MixerInputGroup<\/em> contains individual MixerInput <\/em>objects. Each of those classes have a SetVolume<\/em> method, which allows me to have several levels of volume (aka as Global volume and channel volume) which get multiplied to calculate a final volume to apply in a single mixing pass, avoiding the need to mix at the MixerInputGroup<\/em> level, and then again at the Mixer<\/em> level.<\/div>\n
Although the current design has proven successful, it does have severe limitations in flexibility, has for example not being able to apply an hypothetically<\/span> effect to a single sound or sound group. It’s only possible to apply an effect to the final mix.<\/div>\n
So I decided to go with a new design which should be more flexible, but I’ll still use the old codebase as reference, especially because of the small fixes\/features I’ve implemented meanwhile.<\/div>\n
Some of the new features I’m planning:<\/div>\n
– DSP plugins. Will probably provide just 1 or two as an example.<\/div>\n
– Configurable DSP network. This will make it possible to create a custom DSP network and play sounds in specific point in the network.<\/div>\n
– Streaming support. Only Ogg Vorgis planned so far, but should pave the way for other formats<\/div>\n
– Maybe virtual voices (ala FMOD style), if I get the time.<\/div>\n
<\/div>\n
Again, those features shouldn’t add significant overhead until used, of course.<\/div>\n
<\/div>\n
If the user \u00a0sticks with the default settings, performance should hopefully be comparable to the current version.<\/div>\n
I’ll be dropping support for old Symbian editions (< 3rd edition), which should make some things easier.<\/div>\n
I wish I could drop Palm OS, which is a real pain to develop for, but a particular client still requires it.<\/div>\n
