-The crossovers started replacing analog "Hardware" crossovers in active multi-way speakersThey can also be linearized and are trimmed in time accuracy.+- Neville ThieleProvides a steep separation with a slightly sloping top, whereby undesired frequencies are very well suppressed.\\ 
 +Bessel: These filters have the shortest ringing, which allows the step response to be highly optimized. 
 + 
 +A companion function recently introduced allows the creation of Horbach-Keele crossovers (speakers must be designed with this crossover in mind, or at least fit its requirements by lucky accident) which provide nearly constant vertical dispersion of sound over a broad range of frequencies.

-**Beschreibung:** \\ +**Use:** \\ 
-Mit dieser Funktion werden digitale Frequenzweichen für aktive Mehrwege-Lautsprecher erstellt.+Digital crossovers can be superior replacements for analog "hardware" crossovers in active multi-way speakers. They can also be linearized and fully adjusted for time accuracy. Impulse and step response for speakers using such crossovers can approach theoretical limits.

- +
-   - Eingabefelder für Trennfrequenzen der einzelnen Wege, direkt daneben die Verzögerung in Samples um eine Zeitrichtigkeit der einzelnen Wege herzustellen. +
-  - Es stehen verschiedene Typen von Frequenzweichen zur Verfügung: \\  \\ - Butterworth / Linkwitz: Finden ihre Entsprechungen auch bei analogen Filtern \\ - Neville-Thiele: Sorgt für eine steile Trennung mit flach abfallendem Anfang, wodurch unerwünschte Frequenzen sehr gut ausgeblendet werden. \\ - Bessel: Diese Filter haben mit das kürzeste Ringing, wodurch sich die Sprungantwort sehr weit optimieren lässt +
-  - Auswahl der Phase +
-  - Filterlänge (Höhere Werte ergeben längere, genauere Filter mit längerer Durchlaufzeit. Empfehlung: 44,1kHz-48kHz: 65536 taps, 88,2-96kHz: 131072 taps) \\ DelAIXO: ??? +
-  - Filterformat (Nur falls die verwendete Faltungs-Software keine .dbl Filter verarbeiten kann .pcm wählen) +
- +
- \\ **Verwendung:** \\ Die erstellten Frequenzweichen ersetzen analoge "Hardware" Frequenzweichen in aktiven Mehrwege-Lautsprechern. Sie können außerdem [[:wiki:anhang:anleitungen:linearisierung_von_frequenzweichen|linearisiert]] werden und auf [[:wiki:anhang:anleitungen:ausgleich_von_laufzeitunterschieden|Zeitrichtigkeit]] getrimmt werden. +
