English term or phrase: time-domain pitch period
An encoding method comprising:
obtaining a time-domain pitch period L of an audio signal in a given time period and a time-domain pitch period code corresponding to the time-domain pitch period Land outputting the time-domain pitch period code;

The present invention relates to a technique to encode an audio signal and, in particular, to encoding of sample strings in the frequency domain obtained by transforming an audio signal into the frequency domain.

in every pitch period in the time domain, information corresponding to the pitch period in the time domain is encoded, the remaining MDCT (MDCT (Modified Discrete Cosine Transform) coefficient strings after the extraction of the large components in every pitch period in the time domain are re-arranged.

Une suggestion.

"in every pitch period in the time domain"

Pitch period: période de hauteur tonale

Time domain: domaine temporel

neutral  Tony M: It's not really 'du domaine temporel', but rather 'dans le domaine temporel': we talk about 'in the time/frequency domain' / It's just not correct technical language in this specialist field.

  -> I thought as much, Tony. But note that "du" in this context has a broad meaning that includes "dans le". Our colleague DreamA will chose which one suits best for his text. No big deal.

Reference: pitch period

Reference information:
is a very specific term relating, usually, to the analysis of speech signals.

période de pas returns by far and away the greatest number of Google hits — BUT that includes a great many red herrings, which are not easy to filter out.

période de tonie looks promising, but returns only around 4,000 results — possibly not surprising, given the highly specialist field in which it occurs. Certainly, 'tonie' is indeed used for 'pitch' in certain other contexts too.

période fondamentale returns some 22,000 results on Google — but this term occurs in so many fields, it's difficult to weed out the relevant ones.

All of the above terms appear in a number of patents translating 'pitch period' from original texts in EN.

So far, I have not been able to find any native FR documents about this subject to confirm which technical terminology appears to be the most widespread. I have not found anything to indicate what research is currently being pursued in France.
