Podcast Post-Production: The Key to Professional Sounding Podcasts

In the world of podcasting, content is king. However, even the most compelling content can be overshadowed by poor audio quality or inconsistent production values. Investing time and effort into post-production is essential to ensure your podcast stands out and captivates your audience. Podcast post-production encompasses several stages, including recording best practices, editing, mixing, and mastering, all of which contribute to a polished and professional final product.

In this blog, we’ll explore the key aspects of podcast post-production and provide you with practical tips to create professional-sounding podcasts that will engage and delight your listeners. By following these best practices, you can elevate your podcast to new heights and provide a more enjoyable experience for your audience.

Podcast Recording Best Practices

To ensure a professional-sounding podcast, it is essential to pay close attention to the recording process. Following these best practices will make your post-production work more manageable and result in a better listener experience.

Choosing the right equipment


Select a microphone that suits your voice and recording environment. The two main types of microphones used in podcasting are dynamic and condenser microphones. Dynamic microphones are better suited for handling loud sound sources and noisy environments, while condenser microphones offer a more detailed and sensitive sound, ideal for quieter, controlled spaces.

Audio interfaces:

An audio interface allows you to connect your microphone to your computer and record high-quality audio. Choose an interface with low latency, sufficient inputs for your needs, and good preamps to ensure a clean, clear signal.

Recording software:

Pick a reliable and user-friendly digital audio workstation (DAW) to record and edit your podcast. Popular DAWs for podcasting include Audacity, Adobe Audition, GarageBand, and Reaper. Ensure that your chosen DAW supports multi-track recording and essential editing functions.

Recording environment

Acoustic treatment:

To achieve optimal audio quality, consider treating your recording space with acoustic panels or foam. This will help reduce unwanted reverberation and reflections, resulting in a clearer, more focused sound.

Reducing background noise:

Eliminate as much background noise as possible by choosing a quiet location to record, turning off noisy appliances or electronics, and using rugs or curtains to dampen sound. In some cases, a dynamic microphone can also help minimize background noise.

Recording techniques

Microphone positioning:

Position your microphone correctly to capture your voice clearly and avoid unwanted sounds. For most podcasters, placing the microphone about 6-8 inches from your mouth, slightly off-axis, can help reduce plosives and sibilance. Experiment with different angles and distances to find the best sound for your voice.

Proper gain levels:

Setting the correct gain levels on your audio interface ensures that your voice is loud and clear without distortion or clipping. Aim for an average level between -18 dB and -12 dB, with peaks not exceeding -6 dB. This will provide enough headroom for post-production while maintaining a clean signal.

Editing the Podcast

Editing is a critical step in the post-production process. It involves removing unwanted sounds, tightening up conversation flow, and maintaining listener engagement. Proper editing can transform a raw recording into a polished, professional podcast episode.

Removing unwanted sounds

Breath sounds:

Breathing is a natural part of speaking, but overly loud breaths can be distracting for listeners. Use a noise gate or manual editing to reduce the volume of breath sounds or eliminate them altogether, depending on your preference.

Mouth clicks:

Mouth clicks, lip smacks, and other mouth noises can be irritating and detract from your content. Use a de-click or de-noise plugin, or manually edit out these sounds by cutting or reducing their volume.

Background noise:

Minimize persistent background noise, such as air conditioning hums or computer fans, using noise reduction plugins or techniques like spectral editing. Be cautious not to over-process your audio, as excessive noise reduction can introduce unwanted artifacts and degrade audio quality.

Editing for content

Removing pauses and silence:

Long pauses or periods of silence can make your podcast feel slow and unengaging. Use your DAW’s editing tools to remove excessive silence, while still maintaining a natural rhythm to the conversation.

Tightening up conversation flow:

Edit out unnecessary filler words, false starts, or repetitive phrases to create a smoother and more coherent dialogue. Be mindful not to over-edit, as maintaining some authenticity is crucial for relatability and listener connection.

Maintaining listener engagement:

Keep your audience’s attention by removing content that doesn’t contribute to the overall narrative or message. This may involve cutting tangents, off-topic discussions, or redundant information. Aim to create a concise and engaging episode that delivers value to your listeners.

As you become more proficient in editing, you’ll develop a keen sense of what to remove and what to keep, striking the right balance between authenticity and professionalism. Remember that practice makes perfect, and the more episodes you edit, the better you’ll become at shaping your podcast into a polished and engaging listening experience.

Mixing the Podcast

Mixing is the process of blending individual audio tracks and elements to create a cohesive and balanced sound. Proper mixing ensures that all elements of your podcast are audible and complementary to one another, enhancing the overall listening experience.

Balancing audio levels

Volume adjustments:

Start by adjusting the volume of each track or speaker in your podcast, making sure their levels are consistent throughout the episode. This may involve automating volume changes for parts where a speaker’s volume fluctuates or where background elements, like music or sound effects, are introduced.

Compression and limiting:

Utilize compression to control the dynamic range of your audio, preventing large volume differences between the loudest and quietest parts. This helps maintain a consistent listening experience. Limiters can also be used to ensure that your audio does not clip or distort, which can occur when levels exceed 0 dB.

Applying equalization (EQ)

Enhancing speech clarity:

Use EQ to emphasize or attenuate specific frequencies in the audio spectrum, allowing for clearer and more intelligible speech. For example, boosting frequencies between 2-5 kHz can enhance speech clarity, while cutting low frequencies (below 100 Hz) can reduce rumble and muddiness.

Addressing frequency issues:

EQ can also be used to address problematic frequencies or resonances, such as plosives, sibilance, or room resonances. Be cautious when applying EQ, as excessive adjustments can result in unnatural or harsh-sounding audio.

Adding audio enhancements

Reverb and ambiance:

In some cases, adding a touch of reverb or ambiance can make your podcast feel more polished and professional. Use reverb sparingly, as too much can make your audio sound distant or muddy. Be mindful of the type of reverb you use, as different reverbs can evoke different emotions and atmospheres.

Sound effects and music:

Incorporating sound effects and music can enhance your podcast’s storytelling and set the tone for your content. Be mindful of volume levels and ensure that these elements do not overpower or distract from the spoken content. Additionally, be aware of copyright and licensing issues when using music or sound effects from external sources.

When mixing your podcast, remember that the goal is to create a balanced and engaging listening experience. It’s essential to maintain clarity and consistency while also adding subtle enhancements that support your podcast’s narrative and tone.

Mastering the Podcast

Mastering is the final step in the post-production process, ensuring consistent audio quality, proper loudness levels, and preparing your podcast for distribution. A well-mastered podcast provides an optimal listening experience across various playback devices and platforms.

Ensuring consistent audio quality

During the mastering process, you’ll want to make sure your podcast has a consistent audio quality throughout the episode and across multiple episodes. This may involve applying subtle EQ adjustments or gentle compression to address any remaining tonal or dynamic inconsistencies.

Loudness normalization

Loudness normalization ensures your podcast is at an appropriate and consistent volume level when played back on various devices and platforms. Most podcast platforms recommend a loudness level between -16 LUFS and -19 LUFS. Use a loudness meter plugin in your DAW to measure and adjust the LUFS level of your podcast accordingly.

Exporting to appropriate file formats

When exporting your mastered podcast, consider the file format and bitrate to balance audio quality and file size. The most common format for podcast distribution is the MP3 format, with a bitrate between 96 and 128 kbps for mono and 128 to 192 kbps for stereo files. These bitrates provide a good balance between sound quality and manageable file sizes for streaming and downloading.

In summary, the mastering process is essential for polishing your podcast and ensuring it sounds great on all platforms and devices. Investing time in proper mastering can make a significant difference in the overall quality of your podcast, providing your listeners with an enjoyable and professional-sounding experience.
