Let’s be honest — we’ve all fallen for the “bigger is better” trap at some point, especially when it comes to audio quality. In podcasting, that usually means someone clinging to WAV files like they’re the Holy Grail of sound. And on the surface? Fair enough. WAV is uncompressed. Pure. Pristine. So why would you ever consider “downgrading” to MP3?
Because your listeners won’t know the difference. And neither will your hosting platform. Or Spotify. Or Apple Podcasts.
Let’s dive into the truth behind WAV vs MP3 for podcasters, especially in an industry like ours, where quality and efficiency matter. And yes — by the end of this post, you’ll probably never upload another WAV file again.
📦 What Are WAV and MP3, Really?
Let’s break it down without going full geek mode:
- WAV (Waveform Audio File Format):
- Uncompressed, lossless audio
- Extremely high-quality, but very large file sizes (e.g., 1-hour podcast = 600MB+)
- Ideal for studio editing and mastering
- Not optimized for streaming or web delivery
- MP3 (MPEG Audio Layer III):
- Compressed, lossy audio format
- Smartly removes inaudible sound data to reduce size
- Easy to upload, stream, and download (e.g., 1-hour podcast = 50–100MB at 320kbps)
- Virtually indistinguishable from WAV for listeners
WAV is your raw steak. MP3 is the perfectly cooked burger. If you’re serving a podcast, your audience doesn’t want to chew through a raw steak. They want something that works on their phone, in their car, and on a flaky café Wi-Fi.
🎧 WAV Isn’t “Better” Once It’s Online
Here’s the part most new podcasters don’t realize: Even if you upload a flawless WAV file, your platform will compress it — often to 128–192kbps AAC, depending on the service. Whether it started as WAV or MP3, the end result is the same.
In other words, the “better” quality you think you’re preserving? It gets auto-squashed the second it hits Spotify, Apple, or Stitcher. All you’re really doing is uploading a bigger file and giving yourself more upload headaches.
🧠 Perception vs Reality: Can You Really Hear the Difference?
Let’s test your ears. Can you tell the difference between a WAV file and a high-quality 320kbps MP3?
Statistically speaking, most people can’t tell them apart — especially after streaming compression. Unless you’re listening on $1000 studio monitors in a soundproof room (and even then), the difference is marginal at best.
Plus, let’s be honest — most of your listeners are:
- On AirPods
- In traffic
- Doing dishes
- Listening at 1.5x speed
They’re not chasing sonic perfection. They want:
- Clear voices
- Balanced sound
- No dropouts or lag
That’s it. And MP3 delivers all of that — without the stress of multi-hundred-megabyte uploads.
🎙️ Remote Guests Are Already Lower Quality
Let’s say you do go full WAV-mode and upload studio-grade audio… but your guest is remote, recorded through Zoom or a web call. Guess what?
You’re starting with compressed audio anyway.
Web calls use aggressive compression to prioritize connection stability over fidelity. Add in background noise, jitter, dropped frames, and the occasional dog barking — and you’re miles away from broadcast quality before you even hit “Record.”
Recording it as a WAV file doesn’t fix that — it just preserves a high-quality version of a low-quality source.
If you’re serious about audio quality:
- Use a double-ender (each person records locally, then you combine tracks)
- Or, lean into post-production cleanup and EQ work
- But don’t rely on WAV alone to “make it sound better”
📡 Upload Speed & Storage: The Unsung Villains
In the real world — especially for independent podcasters and adult creators — bandwidth and storage space matter.
Uploading a 600MB WAV file every week:
- Slows your workflow
- Eats into hosting limits
- Fails more often, especially from mobile or slow internet
- Costs more over time if you’re billed per GB
A 320kbps MP3, on the other hand, is:
- Fast to upload (even on average connections)
- Supported everywhere
- Good enough to mix into radio, YouTube, even broadcast
It’s not a downgrade. It’s a smart, efficient choice.
✅ Best Practice: The Pro Podcaster Workflow
Here’s the ideal setup:
- Record in WAV
- Capture clean, uncompressed audio while you record or interview
- Edit/Mix in WAV
- Apply your EQ, normalize levels, and remove background noise
- Export in 320kbps MP3
- Best quality MP3 available, nearly indistinguishable from WAV
- Upload with confidence
- Smaller file, no quality loss on the listener end, faster delivery
Boom. Clean, pro-level workflow. No drama.
🎙 Case Study: Adult Site Broker Talk
If you want an example of a podcast that gets this balance right, look no further than Adult Site Broker Talk.
Hosted by Bruce Friedman — a voice most of you in the adult industry already know — this podcast regularly features some of the biggest names in adult entertainment, tech, and marketing. It’s sharp, insightful, and yes, recorded smartly.
Bruce is living proof that you can run a top-tier podcast without bogging yourself down in file bloat or WAV-purism. He’s also (at the time of writing this) still playfully arguing with me about file formats — but trust me, his show sounds fantastic because he knows when to go high quality… and when to let go.
🔥 Final Thoughts
If you’re recording for a film soundtrack? Use WAV.
Mastering a Grammy-winning album? WAV.
Trying to impress an audio engineer at a conference? WAV.
But for podcasting — especially in the real world of remote guests, limited bandwidth, and content that needs to move fast — MP3 is king.
Start with WAV, sure. Edit with WAV. But export to high-quality MP3 and get that show out to your audience faster, smoother, and without upload drama.
Because at the end of the day? No one’s tuning into your podcast to analyze your waveform. They’re there to listen to what you’ve got to say.
