   Hello, jahcriado.

   Liquid won’t work because it is practically incompressible; the sound pressure waves don’t change the density of the liquid enough to “read.”

   A permanent suspension of particles in gas is too noisy; reverberation is uncontrollable and the pressure waves in the medium become chaotic.

   A moving “ribbon” of smoke or fog gives the pressure waves something to “write” on that is always a clean slate, provided the ribbon moves fast enough.

   This type of mic can look conventional.

   I’m wondering how you could make this more… conventional looking. I could see it working fine if there was a way to do a permanent suspension in air & have the laser shine through it, but I have not seen a gas mix that stays suspended & not condensing or the ratio fluxing. Could a liquid solution be used?

   really? i just have a hard time imagining the measurements in the modulations of smoke to be more ueseful than other possible mediums, just a thought, maybe shine a lazer at a diaphragm that could refract the beam, or is using light to measure sound the proprietary concept here?

   Fantastic work! Tthere are many aplications that I can think of with a bit more development. I am a audio professional (live concert sound and studio recording) and am very excited about this.

   Truly revolutionary. Proof of concept, and still a work in progress. Yeah team!

   synthtube;

   You’re right. Sorry about that.

   We’re upgrading our AV production values for the Prototype Two clips. Coming soon.

   Cheers,

   Dave

   pulling a Thomas Edison with the poem eh?

   This is great, but… Not to be a curmudgeon, but.. For a so called “Audio professional”, the standard and quality of your audio on these videos is absolutely unforgivable. Hire a real sound recordist next time.

   Absolutely amazing! Good luck at AES!

    anmpir;

    I’m hoping some mic manufacturers will be interested. We’ll see what happens at the AES conference & exhibit in New York next month.

    Cheers,

    You make it fundamentally possible, they tidy it up. Is that the plan this time around too? Thanks for the reply!

12. imon2nd on Oktober 2nd, 2009 02:08

    Thanks, anmpir.

    Note that my audio compression patent from 1983 was only one of at least four main contributors to the MPEG Audio Layer 3 standard. Fraunhofer Institute’s work is what made MP3 sound acceptable.

13. anmpir on Oktober 2nd, 2009 02:08

    Wonderful idea & ultimately, super cool! It’s just a prototype, stop complaining about horrid sound quality. If anybody can improve sound quality using this method it’s the guys who invented MP3!

14. skateplanb94 on Oktober 2nd, 2009 02:08

    Yes, hanooter, sorry about that. We will pay more attention to sound quality in our next video.

15. hanooter on Oktober 2nd, 2009 02:08

    wow, for being sound gurus, the sound in this video was absolutely horrible. I could barely hear you in some parts.

16. CaptainRidley on Oktober 2nd, 2009 02:08

    I’m going to keep my eyes on this. This could be huge.

17. imon2nd on Oktober 2nd, 2009 02:08

    You’re absolutely right. The next video, showing Prototype Two will be posted this week and I promise we’ll get the sound of the video clip done properly.

    I’d be more enthused, if the video makers were able to make a video with better sound quality. An off camera microphone, e.g. a lapel mic would greatly improve this clip.

19. imon2nd on Oktober 2nd, 2009 02:08

    Thanks, Mike!

    I have a story about the mic pending at Kuro5hin. We’ll see if they vote it in.

    Cheers,

    Dave

    Hay this is cool you should post a story about this on k5
