With the constructor you can choose the 51 | type of resampling to be done. Simple linear interpolation can be done by setting 52 | linear_interpolation to be TRUE in the constructor. The other two flags are 53 | ignored if this is set. If linear_interpolation is FALSE then some form of filtering 54 | will be done. IF high_quality is FALSE then a small filter will be performed. 55 | If high_quality is TRUE then a large filter (higher quality) will be performed. For 56 | both the small and large filters another parameter can be specified, filter_interpolation. 57 | With filter_interpolation set then the filter coefficients used for both the small and 58 | large filtering will be interpolated as well. 59 | 60 | This class was designed to stream audio data. It also expects audio data as 16 bit values. 61 | Each time a new stream is started some initialization needs to be done. Thus the function 62 | initialize should be called to initialize everything. This initialize function will set 63 | the conversion factor as well as a multiplecation factor for volume. The volume only 64 | applies to the small and large filter. Since this filter uses a history of the audio data 65 | it is possible for it to vary in amplitude. This allows users to scale the data. This 66 | class will work on any number of channels. Once everything is specified then resample 67 | should be called as many times as is necessary to process all the data. The value 68 | inCount will be returned indicating how many inArray samples were actually used to 69 | produce the output. This value can be used to indicate where the next block of 70 | inArray data should start. The resample function is driven by the outCount value 71 | specified. The inArray should contain at least: 72 | outCount / factor + extra_samples. 73 | extra_samples depends on the type of filtering done. As a rule of thumb 50 should be 74 | adequate for any type of filter. 75 | */ 76 | 77 | class aflibData; 78 | 79 | class aflibConverter { 80 | 81 | public: 82 | 83 | // Available contructors and
