最近网络媒体对 [Google 的 Chromecast 音频设备的下架](https://www.theverge.com/2019/1/11/18178751/google-chromecast-audio-discontinued-sale)发出叹息。该设备在音频媒体界备受[好评](https://www.whathifi.com/google/chromecast-audio/review)，因此我已经在考虑入手一个。基于 Chromecast 退场的消息，我决定在它们全部被打包扔进垃圾堆之前以一个合理价位买一个。


我在 [MobileFun](https://www.mobilefun.com/google-chromecast-audio-black-70476) 上找到一个放进我的订单中。这个设备最终到货了。它被包在一个普普通通、简简单单的 Google 包装袋中，外面打印着非常简短的使用指南。

我通过我的数模转换器的光纤 S/PDIF 连接接入到家庭音响，希望以此能提供最佳的音质。


安装过程并无纰漏，在五分钟后我就可以播放一些音乐了。我知道一些安卓应用支持 Chromecast，因此我决定用 Google Play Music 测试它。意料之中，它工作得不错，音乐效果听上去也相当好。然而作为一个具有开源精神的人，我决定看看我能找到什么开源播放器能兼容 Chromecast。


### RadioDroid 的救赎


[RadioDroid 安卓应用](https://play.google.com/store/apps/details?id=net.programmierecke.radiodroid2) 满足条件。它是开源的，并且可从 [GitHub](https://github.com/segler-alex/RadioDroid)、Google Play 以及 [F-Droid](https://f-droid.org/en/packages/net.programmierecke.radiodroid2/) 上获取。根据帮助文档，RadioDroid 从 [Community Radio Browser](http://www.radio-browser.info/gui/#!/) 网页寻找播放流。因此我决定在我的手机上安装尝试一下。


![RadioDroid](/data/attachment/album/201904/17/192648whwjh3e7rjqlhz83.png "RadioDroid")


安装过程快速顺利，RadioDroid 打开展示当地电台十分迅速。你可以在这个屏幕截图的右上方附近看到 Chromecast 按钮（看上去像一个有着波阵面的长方形图标）。


我尝试了几个当地电台。这个应用可靠地在我手机喇叭上播放了音乐。但是我不得不摆弄 Chromecast 按钮来通过 Chromecast 把音乐传到流上。但是它确实可以做到流传输。


我决定找一下我喜爱的网络广播电台：法国马赛的 [格雷诺耶广播电台](http://www.radiogrenouille.com/)。在 RadioDroid 上有许多找到电台的方法。其中一种是使用标签——“当地”、“最流行”等——就在电台列表上方。其中一个标签是国家，我找到法国，在其 1500 个电台中划来划去寻找格雷诺耶广播电台。另一种办法是使用屏幕上方的查询按钮；查询迅速找到了那家美妙的电台。我尝试了其它几次查询它们都返回了合理的信息。


回到“当地”标签，我在列表中翻来覆去，发现“当地”的定义似乎是“在同一个国家”。因此尽管西雅图、波特兰、旧金山、洛杉矶和朱诺比多伦多更靠近我的家，我并没有在“当地”标签中看到它们。然而通过使用查询功能，我可以发现所有名字中带有西雅图的电台。


“语言”标签使我找到所有用葡语（及葡语方言）播报的电台。我很快发现了另一个最爱的电台 [91 Rock Curitiba](https://91rock.com.br/)。


接着灵感来了，虽然现在是春天了，但又如何呢？让我们听一些圣诞音乐。意料之中，搜寻圣诞把我引到了 [181.FM – Christmas Blender](http://player.181fm.com/?station=181-xblender)。不错，一两分钟的欣赏对我就够了。


因此总的来说，我推荐把 RadioDroid 和 Chromecast 的组合作为一种用家庭音响以合理价位播放网络电台的良好方式。


### 对于音乐方面……


最近我从 [Blue Coast Music](https://bluecoastmusic.com/store) 商店里选了一个 [Qua Continuum](https://bluecoastmusic.com/artists/qua-continuum) 创作的叫作 [Continuum One](https://www.youtube.com/watch?v=PqLCQXPS8iQ) 的有趣的氛围（甚至无节拍）音乐专辑。


Blue Coast 有许多可提供给开源音乐爱好者的。音乐可以无需通过那些奇怪的平台专用下载管理器下载（有时以物理形式）。它通常提供几种形式，包括 WAV、FLAC 和 DSD；WAV 和 FLAC 还提供不同的字长和比特率，包括 16/44.1、24/96 和 24/192，针对 DSD 则有 2.8、5.6 和 11.2 MHz。音乐是用优秀的仪器精心录制的。不幸的是，我并没有找到许多符合我口味的音乐，尽管我喜欢 Blue Coast 上能获取的几个艺术家，包括 Qua Continuum，[Art Lande](https://bluecoastmusic.com/store?f%5B0%5D=search_api_multi_aggregation_1%3Aart%20lande) 以及 [Alex De Grassi](https://bluecoastmusic.com/store?f%5B0%5D=search_api_multi_aggregation_1%3Aalex%20de%20grassi)。


在 [Bandcamp](https://bandcamp.com/) 上，我挑选了 [Emancipator’s Baralku](https://emancipator.bandcamp.com/album/baralku) 和 [Framework’s Tides](https://frameworksuk.bandcamp.com/album/tides)，两个都是我喜欢的。两位艺术家创作的音乐符合我的口味——电音但又（总体来说）不是舞蹈，它们的音乐旋律优美，副歌也很好听。有许多可以让开源音乐发烧友爱上 Bandcamp 的东西，比如买前试听整首歌的服务；没有垃圾软件下载器；与大量音乐家的合作；以及对 [Creative Commons music](https://bandcamp.com/tag/creative-commons) 的支持。

OK
Online news outlets have recently lamented the [passing of Google's Chromecast Audio device](https://www.theverge.com/2019/1/11/18178751/google-chromecast-audio-discontinued-sale). The device received [favorable reviews](https://www.whathifi.com/google/chromecast-audio/review) in the audio press, so I had already been thinking about acquiring one. Given the news of Chromecast's demise, I decided to look for one at a reasonable price—before they were all snapped up or thrown in the dumpster.

I found one at [MobileFun](https://www.mobilefun.com/google-chromecast-audio-black-70476) and put in my order. The device eventually arrived, packaged in the usual serviceable but minimal Google wrapping, with a very brief Get Started guide printed on the outside.

I cabled it to my home stereo via my digital-analog converter's optical S/PDIF connection, hoping that would provide the best sound quality.

The setup ran flawlessly, and in about five minutes I was ready to play some tunes. I knew that a number of Android applications support Chromecast, so I decided to test it out with Google Play Music; sure enough, it worked just fine and sounded quite good. However, being an open source kind of person, I decided to see what I could find in the way of open source players that work with Chromecast.

## RadioDroid to the rescue

The [RadioDroid Android application](https://play.google.com/store/apps/details?id=net.programmierecke.radiodroid2) fit the bill. It is open source and available on [GitHub](https://github.com/segler-alex/RadioDroid), Google Play, and [F-Droid](https://f-droid.org/en/packages/net.programmierecke.radiodroid2/). According to the documentation, RadioDroid looks up and plays streams from the [Community Radio Browser](http://www.radio-browser.info/gui/#!/) website. So I decided to install it on my handset and give it a shot.

![RadioDroid RadioDroid](https://opensource.com/sites/default/files/uploads/internet-radio_radiodroid.png)

The installation was quick and smooth, and RadioDroid opened rapidly to display local stations. You can see the Chromecast button (the icon that looks like a rectangle with wavefronts) near the top-right side of this screenshot.

I played around with a few of the local stations. The application reliably played music on my handset's speaker, but I had to futz around with the Chromecast button to get the music to stream over the Chromecast. But stream it did!

I decided to seek out my favorite internet radio station, [Radio Grenouille](http://www.radiogrenouille.com/) in Marseille, France. There are various ways to find stations in RadioDroid. One is to use the tabs—Local, Topclick, etc.—located above the list of stations. One of the tabs is Countries; I found France, with some 1,500 stations, on the list and scrolled—and scrolled, and scrolled—down through the list to find Radio Grenouille. Another way is to use the Search button at the top of the screen; the search was rapid and returned that wonderful radio station. I tried a few other searches, and they all returned reasonable info.

Going back to the Local tab, I scrolled through the listings and learned that "local" seems to be defined as "in the same country." So, even though Seattle, Portland, San Francisco, Los Angeles, and Juneau are closer to my home than Toronto, I didn't see any of them in Local. However, by using Search, I could find all stations with "Seattle" in their name.

The Languages tab let me find all stations broadcasting in Portugues, Portuguese, Português, Português Brasil, Português do Brasil, Portuguẽs, and Portugês. I quickly found another favorite station, [91 Rock Curitiba](https://91rock.com.br/).

Then inspiration struck—it's springtime, but who cares? Let's listen to some Christmas music. And sure enough, searching for Christmas led me to [181.FM – Christmas Blender](http://player.181fm.com/?station=181-xblender). Well, a minute or two of that was enough for me…

So, all in all, I recommend the RadioDroid and Chromecast combo as a nice way to play internet radio on a home stereo at a reasonable cost.

## As for the music…

Recently I picked up an interesting album of very ambient (even beatless) music called [Continuum One](https://www.youtube.com/watch?v=PqLCQXPS8iQ) by [Qua Continuum](https://bluecoastmusic.com/artists/qua-continuum) from the [Blue Coast Music](https://bluecoastmusic.com/store) store. Blue Coast has a lot to offer the open source music enthusiast: music is available by download (and sometimes physical format) without resorting to those grotesque platform-specific download managers; it typically provides several formats, including WAV, FLAC, and DSD; different word lengths and bitrates are provided for WAV and FLAC, including 16/44.1, 24/96, and 24/192, and for DSD, 2.8, 5.6, and 11.2 MHz; and the music is recorded with great care using wonderful facilities. Unfortunately, I don't find a lot of music there to my taste, though I like a few of the artists available on Blue Coast, including Qua Continuum, [Art Lande](https://bluecoastmusic.com/store?f%5B0%5D=search_api_multi_aggregation_1%3Aart%20lande), and [Alex De Grassi](https://bluecoastmusic.com/store?f%5B0%5D=search_api_multi_aggregation_1%3Aalex%20de%20grassi).

Over on [Bandcamp](https://bandcamp.com/), I picked up [Emancipator's Baralku](https://emancipator.bandcamp.com/album/baralku) and [Framework's Tides](https://frameworksuk.bandcamp.com/album/tides), both of which I enjoy. The music created by these two artists hits my sweet spot—it's electronic but not (generally) dance, it's melodic, and it tends to have some great hooks. There are many things for open source aficionados to like about Bandcamp, such as the ability to listen to the work in its entirety before buying; the lack of bloatware downloaders; the amounts shared with the musicians; and its support for [Creative Commons music](https://bandcamp.com/tag/creative-commons).
