5.9 HD-AAC 5 THE PRO-CODEC PLUG-IN

First, in order to see the eﬀect on the noise ﬂoor we input 1kHz and 2kHz tones at -60dB.

As this is a low-level signal at -60 dB, there is no activity on the top ten segments of the

bit meter.

Note the magniﬁed scale down to -180 dB. (ALT +drag down on the dB scale.)

HD-AAC 24 bit with correct dither and truncation prior to the Plug-In.

HD-AAC 16 bit with correct dither and truncation prior to the Plug-In.

Since the input signal in both cases has been correctly prepared prior to the input of the

Pro-Codec Plug-In, no bit activity is shown below the selected bit depth. In these cases,

the lossless layer of the encoded HD-AAC ﬁle is 100% identical to the input signal.
