Some details about this that normally do - * not matter: - * - * 1. At the end of a stream, the remainder of data that did not fill up the - * last 50ms window is simply discarded. - * - * 2. If the sample rate changes during a stream, the currently running window - * is discarded and the equal loudness filter gets reset as if a new stream - * started. - * - * 3. For the album gain, it is not entirely correct to think of obtaining it - * like "as if all the tracks are analyzed as one track". There isn't a - * separate window being tracked for album processing, so at stream (track) - * end, the remaining unfilled window does not contribute to the album gain - * either. - * - * 4. If a waveform with a result gain G is concatenated to itself and the - * result processed as a track, the gain can be different from G if and only - * if the duration of the original waveform is not an integer multiple of - * 50ms. If the original waveform gets processed as a single track and then - * the same data again as a subsequent track, the album result gain will - * always match G (this is implied by 3.). - * - * 5. A stream shorter than 50ms cannot be analyzed. At 8000 and 48000 Hz, - * this corresponds to 400 resp. 2400 frames. If a stream is shorter than - * 50ms, the element will not generate tags at EOS (only if an album - * finished, but only album tags are generated then). This is not an - * erroneous condition, the element should behave normally. - * - * The limitations outlined in 1.-4. do not apply to the peak values. Every - * single sample is accounted for when looking for the peak. Thus the album - * peak is guaranteed to be the maximum value of all track peaks. - * - * In normal day-to-day use, these little facts are unlikely to be relevant, but - * they have to be kept in mind for writing the tests here. - */ - -#include <gst/check/gstcheck.h> - -GList *buffers = NULL; - -/* For ease of programming we use globals to keep refs for our floating src and - * sink pads we create; otherwise we always have to do get_pad, get_peer, and - * then remove references in every test function */ -static GstPad *mysrcpad, *mysinkpad; - -/* Mapping from supported sample rates to the correct result gain for the - * following test waveform: 20 * 512 samples with a quarter-full amplitude of - * toggling sign, changing every 48 samples and starting with the positive - * value. - * - * Even if we would generate a wave describing a signal with the same frequency - * at each sampling rate, the results would vary (slightly).
