| # Frequently asked questions | ||
|
|
||
| ## Filtering | ||
|
|
||
| - I only have filters with negative gain, why do I get clipping anyway? | ||
|
|
||
| If all filters have negative gain, then the | ||
| It's not very intuitive, but the peak amplitude can actually increase when you apply filters that only attenuate. | ||
|
|
||
| The signal is a sum of a large number of frequency components, and in each particular sample some components | ||
| will add to increase the amplitude while other decrease it. | ||
| If a filter happens to remove a component that lowers the amplitude in a sample, then the value here will go up. | ||
| Also all filters affect the phase in a wide range, and this also makes the components sum up to a new waveform that can have higher peaks. | ||
| This is mostly a problem with modern productions that are already a bit clipped to begin with, meaning they have many samples at max amplitude. | ||
| Try adding a -3 dB Gain filter, that should be enough in most cases. | ||
|
|
||
| - When do I need to use an asynchronous resampler? | ||
|
|
||
| The asynchronous resampler must be used when the ratio between the input and output sample rates cannot be expressed as a fixed ratio. | ||
| This is only the case when resampling to adaptively match the rate of two devices with independant clocks, where the ratio drifts a little all the time. | ||
| Note that resampling between the fixed rates 44.1 kHz -> 48 kHz corresponds to a ratio of 160/147, and can be handled by the synchronous resampler. | ||
| This works for any fixed resampling between the standard rates, 44.1 <-> 96 kHz, 88.2 <-> 192 kHz, 88.1 <-> 48 kHz etc. | ||
|
|
||
| - My impulse response is a wav-file. How to I use it in CamillaDSP? | ||
|
|
||
| The wav-file must be converted to raw format, with one file per channel. Please see the [guide for converting](coefficients_from_wav.md). | ||
