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 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).
