Who Am I? ∴ I’m David Klann

I help radio broadcast stations implement tools and apps such as Rivendell radio automation, Icecast web streaming and Linux. I use and contribute to Open Source and Free Software projects. Check out my tools at GitHub Open Source Radio and GitHub David Klann.

I have deep knowledge of and experience with TCP/IP networking from small- and enterprise-scale network design, implementation and security to Linux and UNIX kernel-level implementations and driver development. See my LinkedIn Profile for details about my experience.

Go here if you’re looking for the excellent hardware company Broadcast Tools. The web URLs are similar, but we do very different things for broadcast stations.

“Don’t let your avocation become your vocation!” ∴ My first broadcasting supervisor

Well Jon, I did it.

I started Broadcast Tool & Die after building the online streaming station radiodriftless.org in 2005, full-power NCE radio station WDRT, Viroqua, WI in 2010, and low-power FM WNUC-LP, Detroit in 2017. I learned a lot about digital audio systems and brought my 20–plus years of IT work and commercial broadcast experience to the world of broadcast and podcast. Check out my awesome work, and see more about me.

I turned my avocation into my vocation, and I still love what I do!

Here’s a short list of some of the things I’ve done for my clients.

Rivendell ∴ Radio Automation & the cost of Free Software

I’ve been working with the Rivendell radio automation software for more than a decade. The simple fact is that although it is free software, the real cost of implementing it is your time. I help stations get from “installation” to “up and running” as quickly as possible: Setting up the library, adding trigger events, clocks and a schedule grid, and explaining it all so you can get down to the business of programming your station quickly!

Streaming ∴ Put Your Station on the Internet!

I’ve been hosting radio station audio streams for more than 12 years. It’s easy, uses little bandwidth, and as fun for me as it is for you! I provide RoU reports for SoundExchange in whatever format you need, including so-called “NPR format” (required for submission to NPR digital services under the NFCB agreement). I’ll even hook up your Rivendell automation system to the Icecast server so your listeners get updated stream data!

Reporting and analytics are included in your low-cost monthly streaming fees. Here’s an example of a real-time listener graph. I offer other views and data for your streams.

I can also set you up with and host alternative stream technology, like HLS streams.

RDFetch ∴ Manage and Ingest Podcasts to Rivendell

Stations regularly ask about Rivendell’s ability to download and import audio files from podcast sources. As delivered, Rivendell has no capability to do this, so I wrote RDFetch.

The core of RDFetch is a simple text menu that leads you through setting up downloads and importing podcasts. RDFetch uses the standard Linux tool podget to perform the podcast download. It downloads the audio files into directories (aka “folders”) that RDFetch previously set up as Rivendell dropboxes. When the download completes, Rivendell automatically imports the freshly downloaded file into the library. RDFetch also lets you know when it’s having trouble so you can attend to it before it results in dead air.

JACK ∴ Route the Sounds

It’s a common desire for people to use their Rivendell computer as a general–purpose audio workstation. This requires an industrial–grade audio routing tool such as JACK. I’ve spent many hours getting Rivendell, JACK and other audio apps working together.

Networking & I.T. ∴ If it’s not making you money, it’s costing you money

Get the most out of your investment in technology resources. Make sure your network is efficient and secure. I have many years of designing, building, monitoring and hacking small and large networks. Let me help you with your IT infrastructure so that it contributes to your bottom line.

S?L: Studio to Wherever ∴ Get Your Audio Out The Door

Linking your studio to your transmitter, and other destinations can be dicey: transmitters are often in the middle of nowhere. I can help you get your audio signal from the studio(s) to the transmitter(s) and elsewhere with cost-effective and creative solutions.
