嗨,大家好!我是俄罗斯工程师,我的名字是E1。我们的小型开发团队准备了一个开放的硬件(HW)和免费的IOS应用程序(Android应用即将推出),用于低音炮的DSP控制。 HW是30x40mm 2层PCBA与2 IC - CC2540 Ti BLE和UADAU1761 AD DSP。这种小型PCBA能够完全替代典型的低音炮通常使用的模拟分频器,限幅器压缩器,自动开/关电路和其他功能。 iWoofer HW PCBA只需要具有32mA电流的5VDC(或3.3VDC)电源,因此很容易满足待机模式下的能源之星要求。我们为iWoofer HW免费提供完整的源代码包,还有原理图,PCB(Altium 14)和cc2540的固件ROM。免费的IOS应用程序你可以在appstore找到。 HW PCBA的BOM将达到15-20RMB,具有良好的MP数量,即与通常的低音炮前置放大器成本相当,再加上智能手机的无线控制。该应用程序允许您调整多个DSP参数,保存/导入(从www)/导出(至电子邮件)预设。您可以调整LPF和HPF的频率和顺序(2/4/8),25pcs参数均衡器,压缩器限制器,次谐波合成器,动态低音,相位(第一APF),延迟,自动开/关阈值和保持开启时间。此外,该系统为低音炮的后面板模拟旋钮(HPF / LF / PHASE / BOOST)提供多达四个可配置的硬件控制器。没有任何许可费,100%免费。如果您有任何问题,我将很乐意澄清任何细节,甚至修改iWoofer功能,如果您提供更好的功能。 谢谢。

PS:几周前,我已经发布了关于iWoofer的第一条信息,请访问 http://www.diyaudio.com/forums/s ... em-ios-android.html 现在,这篇文章看过390次,没有一个真正的回复,但最大的惊喜是iWoofer应用程序在中国安装了89次!
E version, in case if Google translate isn't perfect:
Hi guys! I'm a Russian engineer, my name is E1. Our little developing group prepared an opened hardware (HW) and free IOS app (Android app is coming soon) for subwoofer's DSP control. HW is the 30x40mm 2 layers PCBA with 2 IC's - CC2540 Ti BLE, and UADAU1761 AD DSP. This tiny PCBA is able to complete replace an analog crossover, limiter-compressor, Auto On/Off circuit and others functions commonly used in a typical subwoofer. The iWoofer HW PCBA need only 5VDC (or 3.3VDC) power with 32mA current, so it is quite easy to meet Energy Star requirements for the standby mode. We provide a full source pack for iWoofer HW for free, there is Schematic, PCB (Altium 14), and firmware ROM for the cc2540. Free IOS app you can find on appstore. The BOM of the HW PCBA will be around 15-20RMB for good MP quantity, i.e. comparable with usual subwoofer preamp cost, plus wireless control with a smartphone. The app allows you to adjust numerous DSP parameters, saving/import(from www)/export(to email) presets. You may adjust frequency and order(2/4/8) of LPF and HPF, 25pcs parametric EQ's, compressor-limiter, subharmonic synthesizer, dynamic bass, phase (1st APF), delay, Auto On/Off threshold and hold On time. Also, the system offers up to four configurable HW controllers for the subwoofer's rear panel analog like knobs (HPF/LF/PHASE/BOOST). No any license fee, 100% free. If you'll have questions, I'll would be happy to clarify any details, and even modify the iWoofer functions if you'll offer better one. Thank you.

PS: a few weeks ago I've posted the first info about iWoofer at http://www.diyaudio.com/forums/subwoofers/, For now, the post viewed 390 times, no one real reply but the biggest surprise that the iWoofer app was installed 89 times and ONLY in China!
