How to mix and master your podcast with AI

Updated over a week ago

Mixing and mastering your podcast audio is HARD work. That’s probably why you’re reading this article in the first place.

In the past, removing background noise, balancing the volume of speakers, removing unwanted frequencies, and achieving a professional sound for your podcast meant you needed to learn audio production from the ground up. You needed to get a Digital Audio Workstation (DAW), and learn how to use plugins like equalizers, compressors, spectrograms, and more.

It was a LOT of work.

But now, thanks to advances in AI, there’s an easier way. In this article, we’ll show you how to automatically mix and master your podcast with Enhance by Resound.

How it works (Step-by-step)

  1. Log into Resound at app.resound.fm

  2. Upload your file(s)

  3. Resound processes your audio

  4. Open the Resound Editor, click the Editor Settings ⚙️, turn on Enhance, and click apply

  5. Listen to your audio, turning Enhance off if you want to compare before/after.

  6. Review other edits Resound detected (optional)

  7. Export Enhanced file(s) to upload to your podcast hosting app or continue editing

Enhance FAQs

Exporting Enhanced Files

Simply click Export and select the right file format to export an enhanced file from Resound. Resound will export whatever files you are currently listening to in the app. If Enhance is on, the exported files will be enhanced. If Enhance is off, the exported files will be your original audio files.

You can export both a merged Enhanced file in Resound AND individual enhanced files. Simply click the button to include individual tracks when exporting if you wish to do so. The individual enhanced files will sound slightly different than the master file because it has not been run through all the same algorithms as the master merged track. But you will still notice noise reduction and overall improvement.

How do I compare my original audio and Enhanced audio in Resound?

If you want to compare your Original audio to the Enhanced audio, simply click on Editor Settings in the Resound Editor and turn Enhanced off. This will switch the editor back to your old files so you can hear and see the difference. You can toggle this on and off as many times as you want.

How will I know when my file is done Enhancing?

If your Enhanced file is still processing when you click the “Enhance toggle”, you will see an indicator that says “Enhancing” at the top of the Editor. You will also see a message pop up in the bottom right corner of the app once it’s done. If your file is already DONE being enhanced, the file will swap out instantly and you can just click play to hear the results.

How does Resound work behind the scenes?

Resound runs your audio file(s) through a series of audio algorithms powered by Auphonic. We developed this feature in collaboration with a Lead Mixing Engineer from Resonate Recordings to dial in our enhancement algorithm to meet their high-quality standards. The results speak for themselves.

👉 The bottom line? If you export an Enhanced MP3 file from Resound, you can rest assured that your file has been optimized to meet the streaming standard for podcast apps like Apple Podcasts and Spotify. That means it’s been mastered to -16 LUFS and has an 128 kbps bitrate.

Want to know more? Below is an overview of the processing your files will go through in Enhance.

Single track algorithms:

Single track projects run through a simplified series of algorithms and signal processing.

  • Filtering & AutoEQ: Make your voices sound better by removing unwanted frequencies and de-essing them (removing “shh” sounds).

  • Noise & Reverb Reduction: Uses AI to detect background noise and speech, separating them out and reducing the amount of background noise. This includes hum, room reverb, and other background sounds.

  • Intelligent Leveler: Dynamically adjusts the volume across different parts of a single track. This even takes into account the background noise so that those sounds do not get amplified.

  • Loudness Specifications: Automatically sets your podcast at -16 LUFS (loudness units full scale) which is the recognized industry standard for mastering podcasts. Tracks are normalized as a part of this process to ensure a smooth volume across the entire audio file.

Multitrack algorithms:

Multitrack projects run through a more complex series of algorithms and signal processing on their individual tracks and on the master track.

  • Filtering & AutoEQ: Make your voices sound better by removing unwanted frequencies and de-essing them (removing “shh” sounds).

  • Noise & Reverb Reduction: Uses AI to detect background noise and speech, separating them out and reducing the amount of background noise. This includes hum, room reverb, and other background sounds.

  • Multitrack adaptive Leveler (⭐️ multitrack only): Dynamically adjusts the volume of all tracks to ensure that multiple files (e.g. 3 different speaker voices) have an even and consistent volume level.

  • Crossgate (⭐️ multitrack only): Identifies when people are not speaking and mutes those sections to further reduce background noise.

  • Loudness Specifications: Automatically sets your podcast at -16 LUFS (loudness units full scale) which is the recognized industry standard for mastering podcasts. Tracks are normalized as a part of this process to ensure a smooth volume across the entire audio file.
