One crucial factor frequently determines a podcast’s success: sound quality Even if your content is excellent, bad sound can turn listeners away. Fortunately, you don’t need expensive equipment or a professional studio to improve your podcast’s audio quality. You can make a clean, professional-sounding podcast that keeps your audience interested with the right tools and methods. From recording tips to post-production tweaks, we’ll go over the essential steps and best practices in this guide to improve the audio quality of your podcast.
1. Put resources into a Quality Mouthpiece
The mouthpiece is the underpinning of your web recording’s sound quality. One of the most significant improvements you can make is upgrading to an external microphone, even though many podcasters begin with the built-in microphone on their computer.
Condenser versus dynamic microphones: Due to their durability and ability to reject background noise, dynamic microphones are typically preferred for podcasts. Despite being more sensitive and detailed, condenser microphones are better suited for soundproof environments because they can pick up too much ambient noise.
XLR versus USB microphones: Because they connect directly to your computer, USB microphones are great for beginners. On the other hand, XLR microphones have better sound quality and are more adaptable, but connecting them requires an audio interface or mixer.
Microphones that Podcasters Should Use:
Entry-Level: Samson Q2U or Audio-Technica ATR2100x-USB (USB/dynamic).
Mid-Range: (XLR/dynamic) Rode PodMic or Shure SM58
High-End: SM7B (XLR/dynamic) Shure
2. Make Your Recording Space Quiet Even the best microphone can’t eliminate background noise or bad acoustics. It is essential to establish a controlled and quiet recording environment.
Reduce noise from outside: Make an effort to record in a quiet space where you can control external sounds like traffic, pets, or raucous neighbors. Close all doors and windows, and turn off any appliances, such as air conditioners or fans, that make background hums.
Treatment of the sound: Add some basic acoustic treatments if your room has a lot of echo or reverb. Place soft items like rugs, curtains, and pillows around the room to help absorb sound and reduce reflections. You don’t need professional foam panels.
Close-Miking: By speaking into the microphone from a distance of about 4-6 inches, you can reduce ambient noise and keep the listener’s attention on you. A pop filter can be used to reduce “plosives,” which are popping sounds from “p” or “b” sounds.
3. Make use of a pop filter or windscreen Windscreens are straightforward and inexpensive accessories that stop loud bursts of air hitting the microphone from making harsh plosive sounds. When placed in front of the microphone, a pop filter or windscreen can significantly improve voice clarity.
Reasons to Use a Pop Filter: It gives your podcast a more polished sound by smoothing it out and removing the jarring “pops” of certain consonants.
4. Control Your Recording Levels Clean recordings require proper microphone technique and audio levels. While recording too quietly can introduce noise during amplification, recording too loudly can result in distortion.
Adjust Gain Levels: Your voice should peak at around -6 dB on the level meter in your recording software if you adjust the gain of your microphone. This gives enough headroom to keep the audio loud enough without causing distortion.
Prevent Clipping: When the volume of your audio is too high, it distorts and results in clipping. Ensure that your levels never fall below 0 dB while recording.
5. Utilize audio editing software to really fine-tune the audio quality of your podcast after it has been produced. You can clean up noise, adjust the levels, and improve the sound as a whole with editing software. In post-production, some common tasks to improve your podcast’s audio are as follows:
Reduce Ambient Noise: The majority of editing software has noise reduction tools that can get rid of background noises like hums, hisses, and so on.
Standardize the Volume Levels: By normalizing the audio, you can guarantee a consistent volume throughout your episode. This guarantees that all speakers speak at the same volume.
Include Equalization (EQ): The frequency spectrum of your audio can be balanced with EQ, making your voice sound clearer and fuller. To improve vocal clarity and eliminate unwanted rumble, one common EQ adjustment is to reduce low-end frequencies (below 100 Hz).
Compression: Variations in volume are smoothed out by a compressor, ensuring that quiet parts are still audible and loud ones are not overpowering. Your podcast will sound more polished and professional as a result.
Software for editing audio is recommended:
Beginner-Friendly: GarageBand (free for Mac) and Audacity (free).
Advanced: Reaper (paid) and Adobe Audition (paid).
6. Record Each Speaker’s Voice on a Separate Track If your podcast features multiple hosts or guests, you should record each voice on a separate track. During editing, you can control each person’s volume independently and remove any overlapping dialogue thanks to this.
How to Make Multiple Tracks at Once: Separate tracks can be recorded with multichannel recorders or audio interfaces. Tools like Zencastr and Riverside.fm can record each speaker on their own track when recording from a distance, even over the internet.
7. Utilize a Noise Gate A noise gate is an audio effect that automatically mutes or reduces the volume of your microphone when you are not speaking, removing any background noise that might be present in the silence between words. If you’re recording in a less-than-ideal setting, this is especially helpful.
How Things Work: The threshold of the noise gate should be set just below your speaking volume. When you speak, the gate opens and closes in this manner, muting any background noises.
8. Consider Using Music and Sound Effects The production value of your podcast can be enhanced by including intro/outro music, sound effects, or ambient music. However, it is essential to strike a balance—your voice should never be overpowered by background music.
Music Without Charges: To avoid copyright issues, use music that is free or licensed. Music specifically designed for podcasts can be found on websites like Epidemic Sound, Artlist, and Free Music Archive.
Fade Out/In: To keep your attention on the dialogue and prevent abrupt transitions, slowly fade in and out the music.
9. Monitor Your Podcast Using Headphones By monitoring your podcast as it is being recorded, you can spot problems like microphone placement, distortion, or background noise in real time. To accurately reproduce the recording and isolate the sound, use closed-back headphones.
The Benefits of Monitoring: You won’t have to wait for post-production to find a problem if you listen to your voice while recording because you can make immediate adjustments, such as moving the microphone or adjusting your gain levels.
10. Utilize Tools for Remote Recording Guests When conducting interviews with guests who are located far away, it is essential to use tools that provide each participant with high-quality audio. The audio quality of regular phone calls or Zoom calls can be subpar, but remote recording platforms can produce much better results.
Tools recommended: Riverside.fm, Zencastr, SquadCast, and Cleanfeed are all excellent options that record each participant’s audio locally, ensuring that each speaker receives high-quality sound.
11. Do a few test runs to make sure everything is working properly before recording your podcast and practice good microphone technique. Make use of proper microphone technique by speaking directly into the microphone and keeping a constant distance from it to prevent volume fluctuations.
Good Standing: Keep your voice clear and strong while recording by sitting up straight or standing.
Regular Volume: Move as close to the microphone as possible to avoid creating volume inconsistencies that are difficult to correct in post-production.
Final Thoughtful Post-Production, Effective Recording Methods, and Good Equipment Are All Required to Improve the Audio Quality of Your Podcast. These actions, such as purchasing a microphone of high quality and employing noise reduction and compression, can significantly enhance the sound of your podcast. Keep in mind that the audio quality of your podcast is a reflection of your brand, so it’s worth the effort to get it right. If you follow these suggestions, your podcast will sound professional and keep your listeners coming back for more.
