I can accept the recording as evidence that flaccon has a budgie.
flaccon_1.wma:
I'm listening in a sound-proof, anechoic room with an array of 9 sets of loudspeakers powered by 7 amps.
My hearing tops out around 13k, which still exceeds the band-width here.
I'm playing back through an audio-editing app called Twisted Wave, on an Imac desktop model.
Even when I bring down the first annoying bang, and fade out the click at the end -- mostly to reduce annoyance and fatigue --
I don't hear any "budgy" or any other bird chirps.
I hear 1 woman and -- I think, though it's hard to tell -- probably two men.
The man or men do sound like they're speaking German, or something, but not English.
The reason I say this is that with this level of detail -- poor, but adequate for understanding -- we ought to be able to understand English words if that's what's being spoken.
With the aggressive noise-reduction or cell-phone-like data reduction in this recording, clues about ambience are being concealed, so it's hard for me to use one of my skills, which is determining the size and materials of the room by listening. You can see that the waveforms go down to absolute silence between bursts.
However.
It's my sense that all speakers are in rooms, and they are not too far from the mic or mics.
The quality is poor enough that you can't be sure.
The most obvious "chirping" effect is the whistling caused by the gated overtones of the woman speaker's voice. I don't hear an independent bird-sound. That whistling or chirping is very obvious.
I doubt there is something subtle that someone else is hearing that I'm not, given my gear and experience.
(I've recorded and processed a lot of bird-sounds in my day. I also taught electronic music, including basic audio production, at New England Conservatory for six years. I have over thirty-five years of audio production experience of various kinds. My ability to hear flaws generally outperformed the mix engineers I worked with. However, this doesn't mean I'm always right.)
> What budgies? Is there another recording?
I'd suggest making more recordings, as simply as possible, including some sample recordings of flaccon speaking normally, so we have some reference recordings.
