Hi John, Thanks for writing. No, this isn't at all like playing speech from middle of a word or music. Certainly beginning a recording from a waveform that would have abrupt onset would result in a pop or click. Have you listened to the file? I deleted the first 4 s, added a 50 ms fade-in, and the impulse sound is still there. But if you begin the wav file from the beginning, there is no artifact. The impulse-like sound (more gunshot sounding--actually sound of IR itself) is quite loud sounding, though there's no noticeable change in amplitude of waveform. That's why I use "loud" in lieu of intense--it's perceptual. If you take the normal (dry) speech or natural speech recorded in same room where the IR was recorded, no such artifact exists. You might get a small click or pop at middle of waveform--this, again, is normal and equivalent to playing, say, a cosine wave from beginning (big click because of abrupt rise time). Please listen to file if you cand download it. Use any generic wave editor (I use Audition because of big visual and easy to use) and move cursor to various parts of file. The impulse is there--almost everywhere--but only in the processed recording. Again, many thanks for writing. Kind regards and Happy Holidays, Eric

The artifacts are simply side effects of starting playback of recorded speech from the middle of a word. Is this situation going to present itself to a person using a hearing aid? I mean does the device itself act as a noise gate? -- with best wishes, John -------------- next part -------------- An HTML attachment was scrubbed...
