Dither allows you to exchange this rough sounding signal-dependant distortion for a smooth background hiss. - -Some sort of dither should always be used when reducing the word length of digital audio, such as from 24-bit to 16-bit. In many cases the background noise in a recording will act as dither, but dither will still be required on fades and on very clean recordings such as purely synthetic sources. - -Noise shaping makes the background hiss of dither sound quieter, but adds more high-frequency noise than 'ordinary' dither. This high frequency noise can be a problem if a recording is later processed in any way (including gain changes) especially if noise shaping is applied a second time. - -If you are producing an absolutely final master at 16 bits or less, use noise shaped dither. In all other situations use a non-noise-shaped dither such as high-pass-triangular. When mastering for MP3 or other compressed formats be aware that noise shaping may take some of the encoder's 'attention' away from the real signal at high frequencies. - -No gain changes should be applied after this plug-in. Make sure any master output fader is set to 0.0 dB in the host application. - -Very technical note This plug-in follows Steinberg's convention that a signal level of 1.0 corresponds to a 16-bit output of 32768. If your host application does not allow this exact gain setting the effectiveness of dither may be reduced (check for harmonic distortion of a 1 kHz sine wave using a spectrum analyser).""" ; - lv2:port [ - a lv2:InputPort , - lv2:ControlPort ; - lv2:index 0 ; - lv2:name "Word Len" ; - lv2:symbol "word_len" ; - lv2:default 0.5 ; - lv2:minimum 0.0 ; - lv2:maximum 1.0 - ] , [ - a lv2:InputPort , - lv2:ControlPort ; - lv2:index 1 ; - lv2:name "Dither" ; - lv2:symbol "dither" ; - lv2:default 0.88 ; - lv2:minimum 0.0 ; - lv2:maximum 1.0 ; - lv2:scalePoint [ - rdfs:label "Truncation" ; - rdf:value 0.0 - ] , [ - rdfs:label "Triangular PDF dither" ; - rdf:value 0.25 - ] , [ - rdfs:label "High-pass Triangular PDF dither" ; - rdf:value 0.5 - ] , [ - rdfs:label "Second-order noise-shaped dither" ; - rdf:value 0.75 - ] - ] , [ - a lv2:InputPort , - lv2:ControlPort ; - lv2:index 2 ; - lv2:name "Dith Amp" ; - lv2:symbol "dith_amp" ; - lv2:default 0.5 ; - lv2:minimum 0.0 ; - lv2:maximum 1.0 ; - rdfs:comment """Dither amplitude - can be turned down to reduce background hiss at the expense of dither level "pumping" caused by the input signal type and level""" - ] , [ - a lv2:InputPort , - lv2:ControlPort ; - lv2:index 3 ; - lv2:name "DC Trim" ; - lv2:symbol "dc_trim" ; - lv2:default 0.5 ; - lv2:minimum 0.0 ; - lv2:maximum 1.0 ; - rdfs:comment "Fine tune DC offset - can help get best dither sound for silent or very quiet inputs" - ] , [ - a lv2:InputPort , - lv2:ControlPort ; - lv2:index 4 ; - lv2:name "Zoom" ; - lv2:symbol "zoom" ; - lv2:default 0 ; - lv2:minimum 0.0 ; - lv2:maximum 1.0 ; - rdfs:comment """Allows the signal to be faded into the noise floor at a clearly audible level so dither settings can be "auditioned".
