DESPERATELY need help with audio sound for online radio/podc

Postby Rachel123 » Thu Jan 12, 2017 9:38 am

Total noob, so please send in explanations like it's for a child! Also, apologies if this is in the wrong section; it seemed the most appropriate.

1. The shows I do are essentially dial-in shows. They depend A LOT on people calling into the virtual studio to give their 10 cents. My callers call mainly from 3 countries: UK, US and Nigeria. For this reason, even though Spreaker likes Skype (which has rubbish audio for me anyway), I chose to use Free Conference Call as my call-in platform. They offer local numbers for the countries that have my demographic and that works just fine for me.

2. I connect the FCC service to Spreaker via VB CABLE (which is what Spreaker recommends for Skype)

3. I recorded an audio and while my voice was clear (I'm the host and was dialled directly into Spreaker), the callers were not as clear. There was a staccato effect where the callers kept fading in and out. I'm told this is called dropped packets or something?

4. Finally, I need a solution that is easy and internet/cloud-based if possible. This is because we are planning to rotate the hosting of the shows between 3 people and I don’t want them all to have to go out and buy cords and cables etc. None of us are making money from this for now. So if there's stuff that can be downloaded/easy to set-up, then that would be great.

Thank you!

I can't comment on anything but point 3 I'm afraid, but that does sound like data loss.

The audio is transcoded to meet the available bandwidth. So if the line is bad, the software will degrade the signal in order to ensure the most amount of speech can make it through. After all for a phone call most people will be happy to take a degradation of audio quality, as long as they can hear every word that is said.

As your dialing in locally to your service, then your available bandwidth will be fairly constant, so the software will pick the best quality it can and your line will support it.

However for people dialing in long distance we can expect this not to be the case as it's dependent on their service quality.

If your in the states then data traveling from across the water has a more limited amount of options of getting there and transalantic congestion can be a problem alongside the more obvious quality issues that may arise from the service of the person dialing in is using.

Solution? I'm not sure I can offer one. If the service you use allows you to control the quality of the data coming, it may pay off to degrade it slightly overall if it can then give you a more constant throughput as I suspect people will be more tolerant of that over something fading in and out.

Ideally I'd be looking into if the is a service option (either within your current package, or an alternative) that offers a more efficient codec which can offer equal quality with a codec that can optimize the transfer better. If one exists or not, I can't tell you that blindly as I don't know the service your using and it's not my field, so even with that info I couldn't say much more. Hopefully someone else has some experience here they can share.

Hey Pete,

Thanks for your prompt response! A lot of it is fuzzy to me, but I'll try to keep up.

Re: my location - I'm based in the UK. Two of my panellists are based here also, with one in the States. They also have to dial into the conference call platform too and even the UK numbers have the same staccato effect.

Re: codec, does that mean inquiring of Spreaker (the radio platform) or from FCC (the call-in platform)?

Many thanks

The DIY forum is rather specialised and doesn't get too many visitors. I'll move the Topic to the Production forum where it will get more attention. I'll leave a shadow Topic in the DIY forum.

I've always been a fine figure of a man. 25 years ago it was measured by quality, now it is measured in quantity.
