Radio streaming URLs

Radio streaming URLs are used by audio streamers and may change over time.

tuneinLogitech’s Squeezebox and SONOS CONNECT:AMP support the TuneIn app which offers a wide choice of radio stations. MP3 is the most common and most compatible audio format but also AAC, a hi quality format, is used. You can browse for a radio station and save the URL in your streamer’s favourites. However, after a while the station may no longer work for various reasons:

  • the station is no longer available in a compatible stream for your device,
  • it has become inactive or
  • it may become unavailable at the broadcaster’s request, due to geographical restrictions, or commercial reasons.

In case of doubt, go to the TuneIn’s web site and search for the radio station to check if it is still supported by a TuneIn URL or it has been discontinued.

If the radio station has been discontinued by TuneIn, you will need to add the URL manually to your audio streamer.

Beware of the accepted audio formats (mp3, wma, and AAC) and the playlist file extensions (m3u and pls). Sonos devices play streams in mp3, wma, and AAC formats. Pls file extensions work on Squeezebox devices.

Check out the radio station’s website for the most up to date URLs. If the URL is not published, you may find it on listenlive.eu, Radiostreams or look at my short list of favourite stations and URLs that work well on my devices:

Spotify

Spotify offers streaming music and holds a vast choice of popular music. You can download Spotify for free and then log onto their service enabling the on-demand streaming of music. While the use of a facebook account is suggested, it is not mandatory and you can sign up for an account by using an email address only.

Spotify is available on different platforms and devices: PC, Mac, Tablet, Smartphone and audiostreaming devices. To learn more about the features, you can have a look at the user guides.

When using the PC or Mac version, you can listen to all music for free. Spotify  works well on Windows XP, Vista, 7 and 10.

When using other devices, you must use paid subscriptions without ads and with a range of extra features such as higher bitrate streams and offline access to music. We recommend to use this version to fully benefit of the flexibility and quality. Keep in mind that this is a single user account. You can use the same account on all your devices but you cannot listen with the same account to your Smartphone and iPad at the same time.

We are using Spotify accounts on the following devices:

Spotify can also be used on an Android tablet and some Blackberry models.

Enjoy!

iTunes library notes (iTunes 12.x):

The (imported) playlists may appear duplicated; in that case remove all (xml) library files in the iTunes directory except the ‘iTunes Library.xml’ and update the Sonos music library (‘Manage’ menu, ‘Update Music Library Now’).

If after the Music Library update process no imported playlists appear, you may need to re-generate the xml library. More details on the iTunes library files can be found on the Apple support pages.

Audacity with RealTek Audio

Audacity with RealTek Audiomixer

Using Audacity with RealTek Audiomixer on Windows Vista may need some tweaking.

Check in the system tray, the Audiomixer settings:

right-click on the speaker icon in the system tray and select  volume control


right-click on the speaker icon in the system tray and select sound manager (you may also have access to these settings through the control panel)

check the recording settings and select the Stereo Mix as input device

Recording with Audacity

Recording with Audacity (version 1.2.6)

Retrieving the files:

Audacity is a freeware application that allows to record any audio played on your pc.

Download the application from the project site.

By default, the records can be saved in ‘wav’ format. To save the recording in ‘mp3‘ format, you must install the lame encoding (‘lame_enc.dll’).

Download the lame file, here from the bioss site or from the project site or from this codec site.

Configure for MP3 export:

Install the application (run the setup) and save the lame mp3 encoder file (‘lame_enc.dll‘) in a folder on your pc. Then start Audacity and select ‘Preferences‘ in the ‘Edit’ pull down menu. In the preferences menu, select ‘Find Library’ and locate the file in the folder where saved the lame mp3 encoder file (‘lame_enc.dll’):

Adjust the recording configuration:

Start Audacity and adjust the settings to your needs:

  • if you want to record from an audiostream, modify the input from microphone to ‘Stereo Mix
    in case you have issues with this, check  my post about RealTek

  • you may also want to adjust the playback and recording level

  • match the (mp3) recording quality to the streaming quality (eg 96kbit/s)
    note: the higher the quality to bigger the file, the lower the quality the smaller the file




    (below is an example of a radio station, where ‘Instellingen’ provides the streaming quality information)


Start Recording:

First start the recording in Audacity:


Then start the audiostream.

 

Warning: changing the audio level of your pc has a direct impact on the recording audio level – ‘what your hear, is what you get’ – if you turn off the PC speaker (mute), you will record silence.

Stop Recording:

Once the audiostream is finished, stop the recording in Audacity and Export As MP3:

 

Edit the Recording:

Before saving (exporting), you may want to edit the recorded file and cut the non-relevant parts at the beginning and the end.

You can jump to the beginning of the recording:

and cut the non-relevant parts: move the mouse pointer on the track line position from where you want to cut and with the left mouse-button you can select the length of the part:


Export the Recording:

To save the recording , select in the Audacity File menu, ‘Export As MP3’:

The application will ask to complete the MP3 tags before saving the file. It is not mandatory to complete all fields. My recommendation is to complete at least the Title Field:

Iomega ScreenPlay Pro

iomega_screenplay_pro_1tbIomega ScreenPlay Pro Features:

The ScreenPlay Pro supports the following video codecs: MPEG-1, MPEG-2 (HL/ML), .MPEG-4 (part 2), ASP, DivX (3.11, 4.x, 5.x, 6.x, HD), Xvid, MP4.

AVI, MOV, MKV, VOB, and ISO are container formats. Specifically, AVI, MOV and MKV contain file playback information as well as the formats used for audio and video streams.

 

The video commands (play, rewind, forward, slow, etc) work well. Network file system performance is weak.

Issues with H.264

Because the H.264 codec is not natively supported. It is required to use the included transcoding server software to stream the video into a format that the ScreenPlay Pro HD can natively play back.

It is however, recommended, in this situation, to re-encode the video stream of the file into a format that is natively supported by the ScreenPlay Pro HD. This will make sure that the file can be played directly from the device without needing to be connected to a netwok.

Issues with MKV files

Then Iomega ScreenPlay Pro HD does not include native MKV file support. However, you can the Transcode Server software to get around this limitation. Read the article on the Iomega support pages: ‘How do I play MKV files with the ScreenPlay Pro HD?

Issues with GMC = Global Motion Compensation

If you have a file that contains S-VOP’s (GMC), then you would need to re-encode that file.

Re-encoding a file can be done with freeware, such as PocketDivXEncoder.

Issues with Windows 7

Windows 7 has new security policies put in place that forbid incoming connections that do not utilize a new CIFS/SMB (Samba) standard that has been implemented in Windows 7.

Because of this, the problem can be fixed by changing the policies regarding CIFS/SMB connections. I am required to say that you can perform these policy updates at your own risk. This may or may not make your system less secure to other devices on your network, but we will not be held liable for anything that may occur when these default policies have been changed.

There is a guide out there that can be found by doing a Google Search with the term “Windows 7 network file sharing policy fix”. It will guide you, step by step, through adjusting your policy to allow your ScreenPlay Pro HD to connect to Windows 7 public shares.

Firmware version R1.96 should  fix the issues with Windows 7 network shares
