Attiny85 USB microphone

-

hi all,

i've found nice tutorial on making usb studio microphone usb soundcard since have no usb sound card , not willing discard or waste 60% of capability's of usb soundcard thinking attiny85 usb microphone.

only problem can't find information on that. attiny85 digispark has hid devices , can't find microphone. mic's hid too.

did 1 think of that?

shouldn't hard, can't find library or indication on how start such project. attiny85 adc capabilitys should able make nice studio microphone. things 100 250 $ , home music recording nice have  attin85 usb microphone.

i hope may point me in right google search direction, because after 3 hours of searching can't find anything. , again, can't 1 thought it... it's terminology 1 find right stuff...

thnxx already

this going extremely hard, if not impossible. attiny85 never designed usb device, let alone usb soundcard.

without extensive knowledge of usb protocol, it's impossible have show sound device.

usb problems aside, adc performs extremely poorly sound recording. bit depth 10 bits, compared 24 bits professional adcs, , you're lucky if can 8khz sampling rates. need @ least 40khz cover entire human spectrum.

Arduino Uno not uploading

hi guys, so, have arduino uno r3 (not wired thing) when try upload sketch (even empty sketch) first takes long in "uploading..." comes error: arduino: 1.8.0 (windows 10), board: "arduino/genuino uno" sketch uses 444 bytes (1%) of program storage space. maximum 32256 bytes. global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes local variables. maximum 2048 bytes. avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x9f avrdude...

Indesign and MathType fonts

i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
