6.1.2 Bit-stream OVERS Meter
Any form of filtering can, under certain circumstances, increase the peak level of the signal. If your
input is hot, this can potentially produce overloads when the signal is decoded. This effect can be
very easily demonstrated with this plug-in.
The bit-stream OVERS meter can be used to monitor this potential for overload. The post-decoder
level is continually monitored, and the meter indicates levels over 0 dBFS. The bit-stream OVERS
clip LED will indicate that a clip event has occurred. Right-click inside the OVERS meter or clip
LED to select the told time for the clip light and meter peak indicator.
The mix level should be reduced by the amount required to avoid any overloads being indicated.
This may be done manually by lowering the overall mix level, or through use of a Limiter, for
example the Sonnox Oxford Limiter.
It is important to note that the indicated bit-stream OVERS metering and clip LED are provided as
a guide only. If a segment of audio is being looped or cycled, these maximum values are not
exactly repeatable from one loop to the next. Furthermore, in some host applications, repeatedly
rewinding to the beginning of the timeline/audio file will also not result in repeatable maximum
values. The discrepancies in both cases should be minor, and not all audio or codecs will suffer
this.
There is a highly technical reason for this, stemming from the difficulty of synchronizing the start
point of the buffer that is used to input data to the codecs.
