Crossover activ cu PC

[arcgotic]

Salutare!

 

Adaug un topic sa discutam despre crossovere active implementate software in PC.

 

Ce am folosit:

Thuneau alocator.

 

Ce folosesc: SXQ. http://rruitr.home.xs4all.nl/sxq.html

Dati-i un test run, eu sunt foarte multumit.

 

Sistemul actual e tri-amplificat. Woofere H frame open baffle cu difuri de 15, medii si inalte.

Nimeni nimic?

 

OT: incercati player-ul Bug Head Emperor. Mai multe info pe google si mai jos:

[bogdanc2011]

Eu m-am jucat cu PatchMix DSP. E softul cu care lucreaza placa mea de sunet. Nu am decat o iesire analogica, asa ca am folosit-o ca sa testez diferite frecvente de crossover.

Am scos fiecare canal (adica dreapta si stanga) pe cate un canal dedicat in mixer unde am pus cate un filtru (de ex. stanga lowpass, dreapta highpass).

Iesirea se duce in amplificator apoi la difuzoare. Cel de joase pe canalul stanga, cel de inalte pe canalul dreapta. Astfel pot controla independent nivelul fiecarui canal si caracteristicile filtrelor.

Din pacate n-am reusit asta decat pe ASIO, deci trebuie sa folosesc programul de facut muzica pentru redare.

A, si sursa trebuie sa fie adusa pe mono, evident.

Daca ai placa integrata 5.1 poti incerca SXQ-ul, merge f bine pe un Realtek mai nou.

Si ca player, am gasit asta, suna bine bine: http://cicsmemoryplayer.com

[arcgotic]

Tot ca player, HQPlayer este de incercat. E gratuit 30zile.

Postez mai jos un copy-paste din fisierul ce l-am scris cand mi-am instalat crossover-ul activ pe Ubuntu. Poate e util cuiva. Mie mi-a luat ceva timp pana am setat software-ul si m-am gandit sa documentez pasii.

suppress a room mode).  The “woofer” chain consists of a Linkwitz-Riley 4th-order low-pass at 1500Hz, followed by a shelving filter with a gain of 4dB at low frequencies, centered at 150Hz, Q=0.71.  The “tweeter” chain consists of a Linkwitz-Riley high-pass at 1500Hz, a 1.9ms delay (for phase/time alignment of drivers) and 4.5dB of attenuation (to match driver sensitivities).ecasound
