iWoofer = 开放硬件和免费应用程序，用于低音炮的DSP控制

iWoofer

Yes, some customers currently asking us for individualy compensated frequency response by minimum phase FIR(for the lowest latency, that is critical). However, without IOS/Android app, just factory QC procedure will be extended for compensation process. Actually, this is another story, and out of topic..
是的，目前一些客户要求我们通过最小相位FIR（对于最低延迟，这是至关重要的）进行单独的补偿频率响应。 但是，如果没有iOS / Android应用程序，只需要延长工厂质量控制程序来进行补偿。 其实这是另外一个故事，脱离主题

Regarding Analog Devices tools, sorry, I don't understand google translation of your question yet..
...

应该需要工具把cc2540的固件ROM下载到2540吧?还是你可以提供给我带固件的2540?

ok，谢谢！
过年后有打样pcb时就一起做，到时候有不明白再请教你。

谢谢E1，这个项目不错！
我下载了相关文件，传到百度盘上了：

pei99888, thanks. However, I believe if someone can not download something from with my links, then him better do not read that topic at all. Right? ;) By the way, yesterday iWoofer was presented in California for some big customer which planning use our solution in their $1500-2000 subwoofer models.

谢谢。 但是，我相信如果有人不能从我的链接下载某些东西，那么他最好不要阅读这个话题。 对？顺便说一句，昨天iWoofer在加利福尼亚州为一些大客户提出，他们计划在他们的1500-2000美元的低音炮模型中使用我们的解决方案。

One more iWoofer variant, standalone one! Should be useful for DIYers - RCA ins and outs, u-USB-B power(iPhone charger is ok), one button to reset pairing password, merged with LED light pipe, 3D printable case (still not perfect but looks neat).

Hi everyone, I want to share my CM6631A design here. Cmedia is a quite weird company which doesn't have any documentation about their IC's on their www, I believe it is stupid for XXI century. So I got information about that IC essentially from this forum, diyaudio.com and from some russian DIY forum as well. I don't want to start a dedicated thread, this topic is ok here I think. Nothing actually special in my cm6631A implementation, only no redundant parts(only N-mosfet is reserved in case if CM6631 in use) and neat PCB with good low impedance GND plane. BTW, all PCB designs what I saw here or on Taobao were so ugly that I was surprised it works.)) The PCB size is 51x41mm because of my needs to fit that into the existing design(the second floor PCB should be true-digital headphone amp on TAS5558 and 64 LVC gates). You may reduce size to about 49x31mm. Good luck.

大家好，我想在这里分享我的CM6631A设计。 Cmedia是一家相当怪异的公司，在他们的www上没有关于他们IC的任何文件，我相信这对XXI世纪来说是愚蠢的。 所以我从本论坛，diyaudio.com以及一些俄罗斯DIY论坛获得了有关该IC的信息。 我不想开始一个专门的线程，我认为这个话题没问题。 在我的cm6631A实现中没有什么特别的，只有没有冗余部分（如果使用CM6631，只保留N-mosfet）和整齐的PCB以及良好的低阻抗GND平面。 顺便说一下，我在这里或在淘宝上看到的所有PCB设计都非常难看，所以我很惊讶它的工作原理。）PCB尺寸为51x41mm，因为我需要将其应用到现有设计中（二层PCB应该是真正的数字 TAS5558和64个LVC门上的耳机放大器）。 如果需要，你可以减少到大约49x31mm。 祝你好运。

我用ADAU1702板改过一个，用的sigmastudio，但是不太会调节。

菜鸟-小超, sorry, I've tried to translate your text by google but haven't clue what you talking about at all.

Guys, I've got a new idea regarding simple edition(SE) version of the iWoofer app. It's a very simple free app with volume slider and switching of presets for simple users. Presets will contain all DSP parameters as usual but also a few bitmaps-pictures: Logo, Background, and Slider knob. So, if you are subwoofer supplier, even tiny one Taobao shop, you can prepare your own skin for iWoofer SE, and print two QR codes to your gift box - 1st QR named "App for IOS"(or for Android), 2nd QR "model". The user will scan the first QR to get iWoofer SE link on the Apple Inc. appstore, and next, when iWoofer SE started, the app asking to scan "model" QR code and get special presets for the particular model with supplier logo etc. So for today, the iWoofer is most advanced subwoofer BLE DSP control system with unbeatable minimum phase FIR room correction, can be part of your DIY subwoofer project. Even if you are a student, you can outperform any top rated subwoofers on the market, regardless their cost, with your own app!

我对iWoofer应用程序的简单版（SE）版本有了一个新想法。这是一个非常简单的免费应用程序，具有音量滑块和简单用户的预设切换功能。预设将像往常一样包含所有DSP参数，但也包含一些位图图片：徽标，背景和滑块旋钮。因此，如果您是低音炮供应商，即使是小型的淘宝商店，您也可以为iWoofer SE准备自己的皮肤，并在礼品盒中打印两个QR码 - 第一个QR命名为“App for IOS”（或Android） “模型”。用户将扫描第一个QR以获得Apple Inc. appstore上的iWoofer SE链接，接下来，当iWoofer SE启动时，该应用程序要求扫描“model”QR码并获得特定型号的特殊预设，并带有供应商徽标等。因此，今天，iWoofer是最先进的低音炮BLE DSP控制系统，具有无与伦比的最低相位FIR室内校正，可以成为您的DIY低音炮项目的一部分。即使您是学生，您也可以使用自己的应用程序，超越市场上任何最受好评的低音炮，无论其成本如何。

我们马上要上这个项目，准备开始贴片，请问安卓的APK在哪可以下载，烧录器用哪个？驱动在哪下？

iWoofer

darren_j, thank you for your questions. The android version was published right here few months ago, however next week or two will be ready next version and I'll publish it this thread as well. Also, I told in this thread how to upload the firmware to cc2540, you need CC Debugger hardware for that, and Ti free software Flash Programmer.


darren_j，谢谢你的提问。 Android版本几个月前在这里发布，但是下一两个星期会准备好下一个版本，我也会发布它。 另外，我在这个主题中告诉了如何将固件上传到cc2540，您需要CC Debugger硬件和Ti免费软件Flash Programmer。

非常感谢俄罗斯的朋友无私奉献，进来学习一下，不过还没看懂信号流程。

iWoofer

kiven_chen, the DSP signal flow is simple:
Inputs->Merger->Switch (4to1, input/tone_generator/sweep_generator/noise/generator)->Gain_slider->Dynamic_bass->SHS->HPF->Dealay->Phase(1st ord allpass)->LPF->Multirate_FIR(the custom cell)->25_Parametric_EQ->Compressor-limiter->Output.
