N-PRYSM是一种实时再合成器，它使用滤波器组来驱动调谐的正弦振荡器，允许对任何声音进行复音调谐。
N-PRYSM使用实时处理方法通过将指定的频率范围拆分为滤波器组来重新合成，然后对正弦振荡器进行调制以重新合成频率区域。这允许N-PRYSM重新调谐、音调偏移并将输入频率锁定到任何比例。
此PLUGDATA-FX补丁使用数百个过滤器，延迟约为6ms。它使用下采样技术来大幅提高cpu性能，并且dsp经过精心调整，以提供最佳的性能质量比。
首先，矩阵。
这是N-PRYSM的核心，允许您将传入的频率/音符重新映射到八度音阶内的任何其他音符。它在指定的频率区域内对每个八度音阶都这样做。
•您可以手动设置和自动化行。
•矩阵的工作原理如下：
•左>右等于输入音符，所以C-B。
•底部>上部等于输出音符，因此C-B。
•您还可以从一些在大多数情况下都能很好地工作的比例预设中进行选择。
•黑色背景的最上面一行设置了根注释，该注释将矩阵从所选注释开始偏移。
接下来是金额。
N-PRYSM使用从滤波器组导出的瞬态分裂来决定噪声和音调内容。主刻度盘调整此比率，0%将输入信号视为纯噪声，100%将输入信号看作纯音调。
对于具有瞬态或大量噪声的信号，建议找到一个好的中间地带，而较软和纯音调的信号应使用100%的拨号盘。
为了获得更多的混音可能性，您可以使用UI左上角的MIX拨盘。
现在，范围。
谐波重要的内容通常在中频，这是N-PRYSM设计得最好的地方。范围限制器允许您选择要重新合成的频率区域，范围高达7个OCTAVE，从65hz到8500hz。范围越大，使用的cpu就越多，因为N-PRYSM会动态禁用滤波器组中未使用的部分。
您可以抓住左右手柄来调整下限和上限。从两个控制柄的中间拖动可以左右移动整个范围。
滑块ui左右显示的音符代表最小和最大频率。
最后，投球和隔离。
N-PRYSM允许您通过偏移滤波器组的设定频率来对其进行音调偏移，从而产生符合您正在使用的矩阵调谐的音调偏移。这是N-PRYSM独有的，非常强大。
N-PRYSM的一个潜在缺点是使用实时最小相位滤波器，当它们引入后振铃和共振时，会导致它们自己的噪声衰减。
这可以通过ISOLATE拨盘来解决，该拨盘充当每个振荡器的噪声门，切断尾部和潜在的不必要的共振。请注意，ISOLATE也可以创造性地使用！
N-PRYSM is a realtime resynthesizer that uses a filterbank to drive tuned sine oscillators, allowing for polyphonic tuning of any sound.
N-PRYSM uses a realtime processing approach to resynthesis by splitting a specified frequency range into a filterbank that then modulates sine oscillators to resynthesize the frequency area. This allows N-PRYSM to retune, pitch shift, and lock incoming frequencies to any scale.
This PLUGDATA-FX Patch uses hundreds of filters with a latency of ~6ms. It uses downsampling techniques to drastically improve cpu performance and the dsp has been tuned carefully to offer best performance to quality ratio.
First, the MATRIX.
This is the heart of N-PRYSM and allows you to remap incoming frequencies/notes to any other note inside an octave. It does this for every octave throughout the specified frequency area.
•You can manually set and automate the rows.
•Matrix works as follows:
•Left > right equals input note, so C-B.
•Bottom > Up equals output note, so C-B.
•You can also select from a few scale presets that work well in most scenarios.
•The very top row with the black background sets the ROOT NOTE, which offsets the matrix to start from the selected note.
Next, the AMOUNT.
N-PRYSM uses transient splitting derived from the filterbank to decide between NOISE and TONAL content. The main dial Adjusts this ratio, with 0% considering the incoming signal as pure Noise, and 100% as pure TONAL.
For signals with transients or a lot of noise, it is recommended to find a good middleground, while softer and purely tonal signals should use the dial at 100%.
For further mixing possibilities, you can use the MIX dial found on the top left of the UI.
Now, the RANGE.
Harmonically important content is often in the mid frequencies, which is where N-PRYSM is designed to work best. The range limiter lets you select the frequency region that is supposed to be resynthesized, with a range of up to 7 OCTAVES, going from 65hz to 8500hz. The bigger the range, the more cpu will be used, as N-PRYSM dynamically disables unused parts of the filterbank.
You can grab the left and right handles to adjust the lower and upper range. Dragging from the middle of the two handles lets you move the total range left and right.
The displayed notes to the left and right of the slider ui are representative of the minimum and maximum frequencies.
Lastly, Pitching and Isolating.
N-PRYSM let's you pitch shift the filterbank by offsetting their set frequencies, resulting in a pitch shift that respects the matrix tuning you are using. This is unique to N-PRYSM and incredibly powerful.
One potential downside of N-PRYSM is the use of realtime minimum phase filters, which can cause their own noisefloor/decay as they introduce post-ringing and resonance.
This can be addressed with the ISOLATE dial, which acts as a per-oscillator noise gate, cutting off tails and potentially unwanted resonances. Note that ISOLATE can also be used creatively! |
