What Is the Riverside FM Podcast?
Riverside FM (now simply Riverside) is not a single podcast but a browser-based platform for recording studio-quality audio and video podcasts remotely, founded in 2019 by Nadav and Gideon Keyson in Tel Aviv, Israel. The platform's core feature is local recording technology that captures uncompressed 48kHz WAV audio files directly on each participant's device, supporting up to 10 participants in a single studio session. For STEM electronics students and educators building DIY audio hardware podcast setups, Riverside provides the software infrastructure while you supply the microphones and audio interfaces.
Riverside FM Podcast Setup With DIY Audio Hardware: Complete Guide
Setting up Riverside FM with DIY audio hardware requires matching your microphone specifications to the platform's 48kHz sample rate requirement to avoid distorted audio. The platform records each of up to 9 guests on separate audio tracks automatically, eliminating the need for complex multitrack mixing software. Students aged 10-18 can build foundational electronics knowledge by constructing USB microphones using Teensy or ESP32 microcontrollers with I2S MEMS microphones like the ICS-43434 or INMP441.
Key Hardware Components for STEM Podcast Setup
The essential audio interface components for a Riverside FM podcast setup include a microphone capsule (electret, dynamic, or MEMS), preamplifier circuit, analog-to-digital converter (for analog mics), and USB audio controller. According to hands-on testing across 14 microphone models in 2026, top performers share three traits: dynamic or hybrid capsule design, real-time monitoring with zero-latency headphone output, and onboard gain control with visual feedback.
| Component Type | Beginner Option (Budget) | Intermediate DIY Option | Sample Rate |
|---|---|---|---|
| Microphone Capsule | Fifine AM8 USB ($50) | ICS-43434 I2S MEMS + Teensy | 48kHz |
| Preamp | Built-in (USB mic) | MAX9814 breakout board (auto-gain) | 48kHz |
| ADC (if analog) | N/A (digital output) | PCM1808 stereo ADC | 48kHz |
| USB Audio Controller | Integrated in USB mic | Teensy 4.1 (USB audio device) | 48kHz |
| Headphone Monitoring | Zero-latency jack | TPA6132 amplifier + 3.3V supply | N/A |
Step-by-Step Riverside FM Setup Process
- Create your Riverside account: Go to Riverside.fm, click "Get Started," and sign up with email, Google, Apple, or Spotify. The free plan includes 2 hours of recording at up to 720p video.
- Configure studio settings: Inside your studio, open Settings and set Recording Mode to "Audio Only" or "Audio + Video," choose 48kHz sample rate in the Recording tab, and select your USB microphone or DIY audio interface as input.
- Set up your recording space: Use a quiet room with headphones to prevent echo-Riverside runs an automatic tech check for microphone input, camera, and speaker output.
- Select audio inputs: For RØDECaster or DIY interfaces, select "RØDECaster Chat" for input to use Mix Minus feature, preventing your voice from doubling back through Riverside's audio channels.
- Invite guests and record: Share your studio link to invite up to 9 participants, verify each person's settings, then press Record after a 6-second countdown.
- Edit and publish: Riverside's transcript-based editor lets you highlight text and press delete to cut audio/video; download separate tracks for each participant for post-production.
Why Local Recording Matters for Audio Quality
Riverside records local uncompressed audio on each participant's device rather than streaming compressed audio over the internet, ensuring fidelity even if WiFi drops during recording. This means your DIY USB microphone recording at 48kHz/24-bit will maintain professional quality regardless of internet connectivity issues. After recording ends, all files automatically upload to the cloud for editing and download.
DIY USB Microphone Build for STEM Students
Building a USB microphone with Teensy is an excellent electronics project for students learning about I2S protocols, ADC conversion, and USB audio class compliance. The Teensy microcontroller can pretend to be a USB audio device with just a few lines of code, connecting directly to I2S MEMS microphones like the ICS-43434. For analog microphones (electret or dynamic), you'll need a preamplifier like the MAX9814 (with automatic gain control) followed by a stereo ADC like the PCM1808 to convert to I2S digital output.
Microphone Type Comparison for Podcasting
- MEMS (I2S digital): Compact, integrated electronics, direct microcontroller connection, full 20kHz frequency range, but may pick up high-frequency noise
- Electret (analog): Requires 1-2V bias voltage, built-in FET amplifier, slightly flatter frequency response than commercial USB mics, affordable breakout boards available
- Dynamic (analog): Simple moving-coil operation, very low output requiring high-gain preamp, robust for loud environments, missing some high frequencies
Spectrogram analysis shows that DIY analogue microphones may miss higher frequencies, suggesting the ADC may not provide full range, while MEMS microphones reach the full 20kHz range. Commercial USB microphones typically use larger electret capsules (1.5cm vs 1cm DIY) and dedicated chips like RealTek ALC4042 for better sensitivity.

FAQ: Frequently Asked Questions About Riverside FM Podcast
Practical Learning Outcomes for STEM Electronics Students
Building a podcast setup with Riverside FM and DIY audio hardware teaches Ohm's Law applications in bias voltage circuits for electret microphones, I2S protocol fundamentals for digital audio, ADC conversion principles, and USB audio class compliance. Students aged 10-18 gain hands-on experience with microcontrollers (Teensy/ESP32), op-amp circuits for preamplification, power supply regulation with LDOs, and real-world audio signal processing.
For curriculum-aligned learning, the microphone project demonstrates sensor interfacing, analog vs. digital signal chains, and the importance of clean power supply design to prevent noise interference-critical concepts in electronics and robotics education. Testing different microphone types (MEMS, electret, dynamic) and analyzing spectrograms provides empirical data for comparing frequency response and signal-to-noise ratio.
What are the most common questions about Riverside Fm Podcast Setup With Diy Audio Hardware?
What is Riverside FM used for?
Riverside FM is a browser-based remote audio/video recording platform primarily used by podcasters, interviewers, educators, and content creators who need to capture professional-grade conversations virtually with lossless audio and up to 4K video recorded locally on each participant's device.
Does Riverside FM work with DIY microphones?
Yes, Riverside FM works with any USB microphone or audio interface that your computer recognizes, including DIY USB microphones built with Teensy microcontrollers and I2S MEMS microphones, as long as you set the sample rate to 48kHz in both the device and Riverside settings.
How many people can join a Riverside podcast session?
Riverside supports up to 10 participants in a single studio session (1 host + 9 guests), with each person recorded on separate audio and video tracks automatically.
What sample rate should I use for Riverside FM?
You must set both your audio device and Riverside FM to 48kHz sample rate; mismatched sample rates cause weird or distorted audio because the RØDECaster Pro II and similar interfaces are set to 48kHz by default.
Can I record audio-only podcasts on Riverside?
Yes, Riverside lets you choose "Audio Only" or "Audio + Video" recording mode in studio settings, and even if you don't publish video, recording it helps with editing and creating social media clips.
How does Riverside FM's local recording work?
Riverside records uncompressed 48kHz WAV files locally to each participant's computer instead of streaming through the internet, so audio quality stays clean even if WiFi drops; files upload to the cloud after recording ends.
