Getting Your Bassline Right for Broadcast Audio
I've spent years working with radio station audio chains, and one of the most common mistakes I see people making is treating music integration like a separate process from broadcast signal flow. The Auburn basketball radio station situation is a good case study because their setup has some specific quirks that matter if you want clean sound. Most stations run their music through a broadcast automation system, then into a broadcast exciter or stream encoder. The problem is that automated music servers tend to push levels hot. When you layer a bass-heavy track underneath live play-by-play commentary, you get frequency masking in the 60-150 Hz range that makes voices sound muddy. This isn't theoretical. I ran into this exact issue at a mid-market college sports station last season.

The approach that actually works here involves managing your signal before it ever hits the broadcast chain. Start by running your bassline track through a high-pass filter set around 45 to 55 Hz. You're not removing musical content; you're removing subsonic energy that broadcast transmitters can't reproduce anyway but will still consume headroom. That alone gives you about 3 to 4 dB of clean headroom to work with. From there, use a multiband compressor with a slow attack and medium release, focused on the low-mid band between 100 and 250 Hz. Set the threshold so you're seeing only 2 to 3 dB of gain reduction during the bass-heavy sections. This keeps the bassline present without letting it swallow the midrange where human speech lives. The key detail most people miss: don't compress the full mix. Route your bassline through a parallel send so the dry signal still carries the transient punch while the compressed version fills out the body. When I was troubleshooting a similar situation at a SEC-affiliated station, I found that using a dynamic EQ instead of a standard compressor on the low end made a noticeable difference. You can set the dynamic EQ to only react when the bass frequency gets too loud relative to the rest of the spectrum, rather than reducing everything uniformly. That preserved the groove while preventing the bass from spiking into the commentary.
Practical Setup Details
For the Auburn station specifically, they run their music feed through an automation system that already applies some limiting. If you're ingesting their output or building a parallel feed, you need to account for that existing processing. I recommend inserting a transparent limiter after your bassline processing chain but before anything hits the broadcast encoder. Set it to ceiling at -1 dBTP and leave about 2 dB of headroom below true peak. This prevents digital clipping while maintaining enough dynamic range for a sports broadcast atmosphere. One thing that trips people up: check your sample rate and bit depth matching. Auburn's station runs at 48 kHz, which is standard for broadcast, but many music servers default to 44.1 kHz. Resampling in real-time on a busy broadcast day can introduce artifacts that show up as a faint warbling or graininess, especially on headphones. Make sure your DAW or audio server is set to match the station's native sample rate. If you're working with stems or isolated bass tracks rather than the full mix, the workflow changes slightly. You'd want to side-chain the bass to the microphone input so that when the announcer speaks, the bassline dips automatically. Set the threshold so the ducking engages at conversation levels but doesn't create a pumping effect during musical passages. A ratio of about 4:1 with a hold time of 100 milliseconds tends to sound natural for sports radio.

The hardware chain I typically recommend for this kind of work is straightforward. A decent analog summing box or a quality USB audio interface with clean preamps goes between your source and the broadcast processor. The Focusrite Scarlett 18i20 handles this well without introducing noticeable noise floor issues, and it's affordable enough that smaller stations can justify the purchase. Pair that with iZotope Ozone for mastering-grade limiting, and you have a complete chain that sounds professional without requiring a full broadcast engineering degree. I should note where this approach breaks down. If the bassline is already heavily compressed or limited at the source, adding more processing in the chain just compounds the problem. You end up with a flat, lifeless low end that still dominates the frequency spectrum. In those cases, the best move is to request an uncompressed or lightly processed source from whatever music service or production team is supplying the station. If that's not possible, a surgical EQ cut between 80 and 120 Hz on the final mix bus can sometimes recover enough clarity without needing to reprocess everything from scratch. Another limitation: this setup assumes you have control over the audio path. If you're a listener or a casual producer trying to recreate this from the outside, the results will be noticeably different because you lack access to the station's broadcast chain and monitoring environment. The techniques work, but the specific gain staging and equalization decisions are calibrated for their particular equipment and facility acoustics. What matters most is understanding the principles rather than copying exact settings.
