    Device to Broadcast Audio Stream

    I am wondering if someone can point me in the right direction with this. I am looking for a device that can stream my audio feed. I don't want to set up another computer in my home studio. Is there anything like this?

    I was talking to a friend a few weeks ago about the same thing. You said you don't want to use another PC, but the Raspberry Pi is a $25 microcomputer. It has audio in so you can send a line out of your mixer to it. Haven't tried it my self but should be something cool to check out.

    Hey Podnutter. At the GFQ Network we use a Telos Prostream. It allows us to have a rack mounted hardware device that allows us to stream to our audio CDNs.

    Telos is the codec expert, and ProSTREAM puts all of our expertise into a single, integrated streaming appliance. Forget no-name encoders; ProSTREAM uses genuine MPEG encoding algorithms from FhG, the inventors of MP3, to ensure the most artifact-free sound quality at whatever bit rate you choose. You can encode directly to MP3 or MPEG-AAC and feed any Shoutcast-compatible media server, or a Wowza server for streaming to Flash clients.

    And, to make your audio really sing, ProSTREAM comes with sweetening from Omnia Audio, the world leaders in audio processing for broadcast.

    The best part: Telos ProSTREAM is neatly self-contained in a 1RU box. Just slide it into a rack and it’s ready to go – no running your mission-critical audio over crash-prone PC hardware and operating systems.

    The Prostream seems like a really cool device, but dont you think its a little over kill for internet broadcasting?

    Overkill? It depends on what your objectives are. If you want a quality stream, you need quality equipment. Lots of radio stations use the Omnia 9 and Omnia 11 processors. Check the prices on those.
    Please direct all questions for me to the forum so that all can benefit.

    I believe that at $2000 audio streaming device is overkill if you can use a PC to for the exact same thing.

    Well Nick I wouldn't say over kill. There are many reason as to why someone would want to use the Prostream. Its under a grand, gives you Omnia processing, has no noise, and takes up very little space. these are all very important features to anyone who is broadcasting. there is no such thing as "overkill" when trying to create a high quality sound.

    To create streaming audio, you can even use a PC and free software, such as edcast (for Windows). Indeed, I'm running edcast with the free Lame MP3 encoder to feed Nashville's NOAA weather radio station to Wunderground.com.

    Another option is non-free encoding software such as that from Spacial Audio. Good stuff! I used to use Spacial's $79 encoder (can't recall the name now) some years ago. -- Oh, yeah - SimpleCast. Good product. Not offered any longer.

    Now I'm using Omnia A/XE at all my stations. It's $395 for a single license and runs in several flavors of Windows. I run it in XP. The audio processor that's included is quite good, and designed specifically for psychoacoustic encoding to follow.

    On my stations running Omnia A/XE, I'm using PCs that we already had doing "utility work" anyway. IOW, I didn't buy any PCs to run Omnia A/XE on. Already had hardware that would work.

    If I didn't already have a PC that would work well, and I was managing anyway with anti-virus, updates, reboots, etc., THEN I would opt for an "appliance" solution - the Telos ProSTREAM. No anti-virus, no monthly updates just to keep the malware away, no fans to wear out, etc.

    If your TIME is worth something, then the appliance approach can make good sense. If your time investment doesn't matter so much, then a PC-based solution is fine.

    BTW, no free (or very cheap) software could possibly provide you with real-deal, licensed encoding software. Fraunhofer and others don't give that stuff away. You can use Lame as an MP3 encoder, but then all you get is MP3, which is 1990's tech, and we have much better now. if you want to stream in HE-AAC v2 - or any AAC flavor - then you'll have to pay some money for the encoder.

    Think of the audio processor/encoder as your FM exciter. You can get a cheap one for $100 on ebay. If your FM competition is using an Omnia 11 feeding a Nautel, Harris, or BE exciter, you better not bring a quirt gun to a shootout.

    All that said - focus on your content! It's really the key thing!
