Hi again, We don't broadcast publicly, so I can't share a link, unfortunately, but we do use broadwave as a studio-to-transmitter link and for remote management by our station manager. I'm happy to help as required, though I don't visit the forum every day. (I'm a happy user, no connection with NCH, despite the number of posts of this forum!). You probably don't need to buy a new router, it's worth starting to look at the one you've got. If you get stuck, send me a private message via the forum with a link to the user manual online.

Hi SFM, Welcome to the forum. Almost any router/modem can be configured to work - you need to ensure that it allows "port forwarding" to be configured. Some do this explicitly, others are configured in two stages. I haven't used either of the two you mention, but in My Netgear DG834G, it needs to be configured in two stages, firstly to define a "service" which identifies a port number or range or port numbers for a specific purpose, and then set up a "firewall rule" to divert incoming traffic for the specified service to a predetermined local address. It's also very useful if you can define a fixed local IP address for the PC running Broadwave. If you can listen on another PC on the same network, it confirms that Broadwave and that PC are set up correctly, you just need to consider the router. Note that some home routers do not support "NAT Loopback". That means that you cannot specify your external IP address locally - you can only use it if you are outside your own local network. Also, note that some ISPs will block traffic on selected ports. The default port 88 used by Broadwave is blocked by some ISPs, particularly mobile data networks, so I recommend you use a different one, e.g. 8818 or similar number, which is not assigned to another service (as 88 is). Going back to the routers you mentioned, have a look at the manuals and check you've got port forwarding set up correctly, and try a different port number too, just in case. If you have any questions on what I've written, just add a reply and I'll try to answer when I can.

Hello zman, Assuming you can play existing audio files correctly, the problem probably lies with the selection of the sound source for the live stream. Is the level bar meter shown to the right of Broadwave Live 1 moving? If it is, you just need to select the URL you get on the info page when you click on Connect. You may need to change the file extension from asx to mp3. If it's not, then you need to select the sound sounce to be the "stereo mix" from your soundcard, or the line-in connector, depending on where the sound is coming from. Have a look at the information in this post: http://nch.invisionzone.com/index.php?showtopic=13101 Let us know how you get on!

Hello acechan, Yes, Winamp & ZaraRadio are "just players" which generate sound on the "stereo mix" output of your soundcard, i.e. the sound you hear if you plug in speakers. Broadwave is "just a streaming server" program that can stream out the audio from your soundcard (via the "live" stream), or can serve up a pre-existing audio file from the appropriate folder on the hard disk, assuming the URL issued to Broadwave specifies an existing file. The clickable link on your website is just a URL which tells Broadwave what to do. An example would be (without the spaces) http:// yourIP : portnumber / broadwave.asx ? src=pplaylistfilename to serve up a pre-programmed (by you) list of audio files, Or http:// yourIP : portnumber / broadwave.asx ? src=ffilename to stream an audio file called filename, Or just stream the live sound from your soundcard: http:// yourIP : portnumber / broadwave.asx ? src=1 etc If you choose the live option, you need a program like winamp or Zara to generate the audio, or in fact any other audio player. So, depending what links you have on your website, you could have any or all of these different options. Hope this helps.

i think the problem was his mobile phone network. I got it to work to my phone using port 88, however his network blocks port 88 to phones, as this port is also used by Microsoft for domain authentication, and that would not be permitted to phones. It didn't surprise me that his network blocks port 88.

Actaully, I've re-read your original post, and think that I may have misunderstood. With Broadwave you can stream the live audio from Line In, or can serve up existing files from the hard disk if you know their name. If you are looking to deliver a program of music to the speakers of your PC and also stream it to allow others to hear it, then Broadwave will do the streaming bit. Many people use another program to generate the music, for example Zara Radio which is a radio automation program. I think that NCH's Zulu DJ software may also do that, but I haven't used it so cannot offer advice there.

Hi yes, I believe it can. I use BW for streaming live audio, but I know it can relay files stored on the computer provided they are in the correct folder(s). Why not download it and give it a try. There are a few people ont he forum that can hlep if youhave a question, though we don't always look at it every day so please be patient. If you are using Windows 7, have a look at my two posts on setting up the streaming ports and selecting the audio source.

It should be using the same port, so if you can hear pre-recorded files, then the Broadwave and firewall config seem to be ok. Maybe it's the selection of the live sound source that is the problem. Look at this post to see if it helps: http://nch.invisionzone.com/index.php?showtopic=13101

Based on what you told us, it's difficult to diagnose. Can you connect locally - i.e. from another PC on the same local network? Have a look at this post: http://nch.invisionzone.com/index.php?showtopic=13099 When it asks whether you want to open or download broadwave.asx, select Open, and it shoudl either play in the browser or open a player such as Win Media Player or Winamp.

Hi, I was helping a friend set up Broadwave, and we got it working internally, i.e. we could connect from another PC inside his network, and it worked when we connected from another PC across the internet, however when we tried to connect to his music stream from a 3G mobile phone, it refused to connect. We eventually found out that the network provider blocks port 88 (which is normally used for the kerberos security protocol), and it's also the default port number used by Broadwave. Instead we chose another port number, in the 8000+ range. We configured Broadwave to use that number, changed Windows Firewall settings, and updated the port forwarding configuration of his internet router. And this time it worked when we connected from the phone using the 3G data network. So, I though I would post this useful tip - that the default port of 88 may not necessarily be the right port number to use in all cases!

Hi, I use Broadwave and Zara too, and I can't see any reason why Sam won't work, as long as you are streaming the playback mix from the soundcard. Have a look at this post which may help: http://nch.invisionzone.com/index.php?showtopic=13101

Hi, I have it working on Windows 7, see my post here: http://nch.invisionzone.com/index.php?showtopic=13099

Hi, welcome to the forum, That URL works fine for me (using Firefox on Ubuntu), so my assumption is that having had the VPN connected, you have some sort of static route defined. Try rebooting the laptop and try to connect to the stream without dialling the VPN first.

Hi First, you need to work out whether it's your router/firewall, or your website. Ask your friend to try http:// your ip address:port/broadwave.asx by typing that URL in to Windows Media Player (or ...../broadwave.mp3 if you listen with winamp). If that works you will see him connect in Broadwave's log screen. If it doesn't work, then it's your router/firewall's port forwarding that needs configuring. You may not necessarily be able to use your own PC to connect with that URL, as it will not work from inside your network if your router does not support "NAT loopback". Some do, some don't. If the above URL works, then it's the code in your website that needs configuring. Good luck!

Winamp works for me if I specify mp3 in the URL, for example: http://ipaddress:port/broadwave.mp3 for the main live stream, or perhaps http://ipaddress:port/broadwave.mp3?kbps=24&src=fFILENAME for example

Hello Dee, Yes, you are limited by your connection's upload capacity, so work out the ideal bitrate you want to give the listeners and divide that into the upload bitrate. In practice, solutions like Broadwave are great for a smallish number of attached listeners, but anything more than "several" needs something like shoutcast. In that option, you stream from your studio to a third-party streaming server, to which the many listeners connect. The third party has more bandwdith than you, so can handle the many connections. Usually you pay a subscription based on the maximum number of listeners you anticipate. I'd recommend using a third-party service initially to gauge demand, before implementing your own Shoutcast server. But even before that, try Broadwave as a "proof of concept" solution as it is very good, until you hit the bandwidth or connection limits.

You could either ask your ISP for a fixed IP address, or sign up to a service like dyndns.com.

It sounds as if your PC being given a different IP address by your router each time it starts. Check it using the command-prompt command "ipconfig". If this is the problem, consult your router manual to fix the IP address allocated, or set it manually on the PC.

Hi, Yes it's possible to use this type of set-up, with Broadwave at the transmitting end and something link ZaraRadio, Winamp, etc at the receiving end. In this configuration, ZaraRadio/Winamp makes and outgoing request to the Broadwave (transmitting) end to "pull" the stream. however there are a few caveats: - there's an encoding delay of 20 - 30 seconds, so no good for a live two-way link, but for a simple "live" stream it's not a problem. - if the transmitting end does not have a fixed IP address, you would need to set that IP address at the receiving end each time you connected. This is ok if it doesn't disconnect and re-connect during the broadcast (e.g. if you are using 3g data via mobile phone). - the internet connection at the transmitting end would need to allow "port forwarding" to allow the receiving end to connect. To avoid the last two problems, you would need to use a "push" stream rather than "pull". Your laptop at the transmitting end could run a Shoutcast or Icecast server to push the stream to the studio. I haven't set this up so far as the Broadwave option works for us. There are also hardware options too, if you can afford them they are well worth the money, such as the Barix Instreamer (for the transmitting end) and Barix Exstreamer (for the receiving end). A Broadwave to Exstreamer link works well. These pair of devices can be configured to operate both a push or a pull configuration.

In Windows 7, you would to the following, it's probably similar in Vista (I've not tried Vista). - right-click the audio icon in the system tray, select recording devices. - right-click Rec Playback and select it as the default device. The mic is selected by default, and that's why you stream the mic. Broadwave will stream whatever you play, as selected in the recording devices. Rec Playback means whatever is selected in the Playback, and will play Windows Media Player, iTunes, etc.

Hi Set the windows "recording control" to "stereo mix" and broadwave will relay what ever sound is the result of the Windows playback mixer into live stream 1.

Seems like something is trying to attach to that port. Try first of all disconnecting the internet connection (unplug the router fromt he phone line) and see if it stops. If it does, then use either the router's logging or a program like Wireshark to see where the connections are coming from. You'll need to know your local address and Wireshark will display the source IP address. The use http://whois.domaintools.com to find out who is originating the external connections.

Hi Peregrine Provided the audio from the H.264 feed is accessible on the PC, it will work. By accessible, I mean you can connect speakers, modify the playback audio settings in Windows and you'll hear it. Broadwave's live stream is controlled by the "recording control" in Windows, and you should select either "stereo mix" (or similar, being the playback output), or hte line in if appropriate.

Hi, Depending on which static IP your broadwave pc is using E.g. wireless or wired, you need to connect to that IP if connecting locally (i.e. from within the same network at home). And you will need to configure the firewall rules in the DG834 to the lan server address corresponding to the static IP address of the broadwave PC. Finally, some of the newest firmware versions for the DG834 don't allow NAT Loopback. NAT loopback is when you try to connect locally to a local server (e.g. your broadwave server) using your public ip address rather than your local static address. If the public address works locally and from outside, then NAT loopback is enabled. If the public address only works from outside your network, then NAT loopback is disabled.

Hi again, I'm assuming you have Broadwave relaying the "stereo mix" from your PC, i.e. whatever the PC is playing, so you can link anything, e.g. mics, audio in (using the Line In jack) or any other sound source. For "any other sound source" you might be using Winamp to play MP3s, for example. In my case, I relay audio from an external location, and you can use Winamp to listen to that location, just by specifying a URL, the URL for the remote source. These remote sources could also be using Broadwave too. I use the radio automation program ZaraRadio, which can select a variety of sources, live and pre-recorded, and then use Broadwave to relay the output of ZaraRadio onwards to the transmitter.
