Hei og takk for at du tar deg tid
Jeg kan ikke velge integer mode i high sierra.
Jeg kjører ikke upsampling.
Hvis vi holder oss til iZo, så har jeg prøvd litt forskjellig, men nå skal jeg teste ut ditt screenshot.
Jeg vil ellers gi deg rett i at parameterne står beskrevet i manualen. Problemet er bare at jeg ikke forstår hva det betyr i praksis.
Du må gjerne forklare hvis du har tid:
For iZotope 64-bit SRC, you have access to advanced detailed parameters to tune the sample rate converter filters:
- Steepness: steepness of the transition band of the lowpass filter. Higher steepness will reject unwanted frequencies but cause more ringing in the time- domain and a higher CPU load
- Max filter length: controls the memory (and CPU usage) used by the resampling filter. Default value (500k) should be sufficient for most applications. Can be increased for getting vey high quality output for very high sample rates (e.g. DSD downsampling)
- Cutoff: cutoff frequency is computed by multiplying the Nyquist frequency by the value of the cutoff scaling parameter. Larger values of cutoff scaling offer a flatter pass-band, while smaller values offer better aliasing suppression
- Anti-Aliasing: the amount of suppression in the lowpass filter’s stop-band. Any frequencies in the stop-band, which are not fully attenuated, will result in aliasing, which is when these unwanted frequencies are mapped to different frequencies and mixed into the output. Use higher values for better quality and use lower values to minimize CPU load.
- Pre-ringing: all lowpass filters are characterized by the amount of ringing they introduce into their output. The steeper the filter, the greater the amount of ringing. There are two general types of ringing: pre-ringing and post-ringing. Pre- ringing will smear transients earlier in time, while post-ringing will smear transients later in time. This control allows users to select pre-ringing, post- ringing, or anywhere in between. A value of 1.0 produces a linear phase filter with equal pre- and post-ringing. A value of 0.0 produces a minimum phase filter, which offers no pre-ringing but has non-linear phase distortion, which can be objectionable. Setting intermediate values allows a continuous tradeoff between pre-ringing and post-ringing and allows users to linearize phase in the pass-band as much as possible.
