    Just curious if there’s a way to disable the 19KHz pilot protection? We intend to use this for webcasting.

    And along the same lines: Can I set the bandwidth higher than 16 KHz, so we can do a high-definition feed?

    Hi Celar!

    Actually you can’t — the pilot protection is the only thing preventing using BBP for mastering CDs, and I intend to release a mastering clipper later. 🙂

    However, you really aren’t missing much. I do hear up to 18 kHz, but i don’t hear a lot of difference between 16 and 18. The 16 kHz output in BBP is actually flat all the way up to 16, and rolls off *above* — as opposed to starting the roll-off before 16 and already being severely attenuated *at* 16. This makes a big difference.

    The other important thing is allocation of available bits in a low bitrate web stream — in reality, few people hear above 16, and by removing what most people can’t hear, more bits are retained for the things that people do hear.

    Breakaway Live will not have limited bandwidth — I should have a beta version out in a few weeks, so you’ll be able to compare them then and see which one you prefer.

    How right you are. I just ran some tones, and discovered that I can’t even hear 15 kHz.

    I can’t hear 15! That is PATHETIC. 🙁
