Re: [LAD] [LAU] First release of jkmeter

it would be nice to see something like this integrated into ardour, at
least in the output channels as an option. i'd like the ability to get
a standard reference level to compare against apart from the 'ok, it
has clipped now, turn it down a tad' level it currently shows :)

>> For the K-20 meter it is 20dB down, for the K-14

>>
>> As of release 0.4.0, both japa and jnoise provide

>> The current release does not include the 22kHz

>> 96kHz and higher.

>> Enjoy !
