Abstract
A multi-channel model train sound reproduction system, in which digital sound files are assigned to a particular channel. The channel assignment may be fixed or variable depending on operation state. For the variable embodiments, channel assignment is preferably done in real time according to the configuration that will produce the highest quality sound reproduction.
Claims14
A method for selecting a channel for the playing of a digital sound file in a model train, comprising:
- (a) providing a sound controller, including,
- (i) a processor,
- (ii) a first sound channel connected to said processor,
- (iii) a second sound channel connected to said processor,
- (iv) a sound memory connected to said processor;
- (b) said processor determining a channel load for each of said first and second sound channels;
- (c) said processor retrieving a digital sound file from said sound memory;
- and
- (d) said processor routing said retrieved digital sound file to a sound channel having the lowest channel load.
