The samples of one channel, as a Haro list. DATA, so To... is right. Be aware this crosses the FFI once per sample -- fine for a look at a few thousand frames, wrong for a whole song.aucune extension

verbs that change the sound ---------------------------------------- Resample to a new rate. QUALITY is sinc unless you ask otherwise -- SN1 measured sinc at 97x the accuracy of linear for 26x the cost, and still 150x faster than real time, so it is the right default.QCSXTZZZIBWU

The symmetric half of loading from memory, and its absence was a real gap: a sound could be decoded FROM bytes but not encoded back TO them, so handing a buffer to another tier meant a temporary file. VC1 went to some trouble to keep a voice out of the filesystem; without this, VC3 would have put it straight back to feed a recogniser.aucune extension

16-bit by default: it is what everything reads, and SN1 measured the round-trip error at 4.18e-5, one quantum. Ask for 32 when you are handing the file back to another stage rather than to a listener. ADD another sound into this one from pnSeconds in, scaled by pnGain -- notes laid on a timeline. Refused when the sample rates differ: a note mixed at the wrong rate would be a different pitch, silently.aucune extension

hearing it ---------------------------------------------------------- PLAY IT, and wait for it to finish. There is no sample-player in the engine -- the device sink plays a STREAM -- so the face builds the smallest graph that can carry this sound and runs it. That is what a declarative face is for: the caller says "play", not "make a graph, start a producer thread, open a device, wait, then take it all down".aucune extension

To...() because these RETURN things. A spectrum is a stzSoundGrid: rows by columns of numbers, with x_step and y_step saying what a row and a column MEAN. Drawing one is the graphics plane's job, and keeping that boundary is what makes the analysis assertable -- "the 1 kHz sine is in the 1 kHz bin" is a claim about numbers; "the picture looks right" is a claim about nothing. The magnitude spectrum of one window. Default 4096 points: about 12 Hz resolution at 48 kHz, which resolves musical pitch without smearing time.aucune extension

(sans commentaire dans la source : le nom se lit comme une phrase) to spectrum ofaucune extension

Frequency against time: one row per window. MULTICORE by default -- every row is an independent FFT over a different slice of the same immutable buffer, which is the one analysis here that parallelises without an argument.aucune extension

(sans commentaire dans la source : le nom se lit comme une phrase) to onsets ofaucune extension

Beats per minute, or -1 when there are too few onsets to say -- which is a better answer than a confident number derived from two events.aucune extension

The standard's K-weighting coefficients are specified at 48 kHz, and the engine REFUSES any other rate rather than applying them anyway. So the face resamples a COPY when it has to -- the caller's sound is not touched, and nobody gets a plausible-looking wrong number.aucune extension

MomentaryLoudness is the standard's own 400 ms window, ungated, taking the LOUDEST such window rather than a mean -- averaging an earcon against the silence around it answers nothing. BS.1770 arithmetic used as specified, so it is LUFS without qualification.aucune extension

(sans commentaire dans la source : le nom se lit comme une phrase) short term loudnessaucune extension

The same K-weighting and the same formula over the sound's OWN length. NOT a standard LUFS figure, and LoudnessMetric() says so -- because the alternative is answering the standard's question wrongly instead of answering a different question honestly. A 60 ms earcon at peak 0.5 reads -9.26 here against -9.27 for the same tone at 400 ms: the two agree to a hundredth of a decibel where the standard has an opinion, which is what makes this trustworthy where it does not.aucune extension
