Unlocking the Mystery Of Podcast Audio

By Tom Seest

Are Podcasts Mono Or Stereo?

At PodcastBig, we help new podcasters develop strategies to create content, traffic, and revenue from podcasts based on our experiences and experimentation.

Podcasts are audio recordings available to download or stream for free, covering any topic imaginable from movies to knitting to running a business.
Podcasts can range from just two people discussing their favorite movie to fully produced productions featuring music, sound effects, and professional editing.

Do Stereo Podcasts Sound Better?

When creating a podcast, the file format for episodes must be carefully considered. Your podcast platform might require one file type over another or you might prefer keeping their quality at a maximum level. File compression can help reduce file sizes without impacting sound quality – just be sure that your listeners receive audio of an appropriate size and sound quality!
MP3 and AAC are two popular podcast file formats. MP3 allows for bitrate-based editing that lets you choose between different bit rates that determine file size and quality; higher bit rates produce clearer audio, but create larger files. Lower bit rates produce smaller files that may sound muffled and subpar compared to their higher counterparts.
Your choice of bit rate depends on how many people listen to your podcast and their download speeds. For maximum impact, try selecting a higher bit rate so listeners can enjoy it even on slower connection speeds.
For most podcasts, a mono mp3 at 128kbps should suffice as the optimal file type for voice-only podcasts, delivering optimal file sizes without compromising audio quality. You can experiment with various bit rates and sample rates until finding something that sounds best; just be mindful not to overcompress, as this may cause a noticeable reduction in audio quality.

Does Spotify affect podcast loudness?

The loudness of your podcast is an integral component of its audio quality. It determines how easily listeners can hear it and influences how loud or soft its music or voices will sound; too loud or too quiet audio may make listening difficult or lead to listening fatigue in certain individuals.
Most modern audio interfaces and recorders allow the user to set an input level, which controls how loud your recording will be. Unfortunately, too loud of an input level results in a loss of dynamics that compromises audio quality significantly.
If your podcast is too loud, it may also cause issues for listeners on mobile devices who try to listen. Most mobile phones lack audio processing software that can deal with extremely loud or soft sounds that might damage hearing and cause distortion; therefore, without proper volume correction your podcast listeners may find it very hard to enjoy it on mobile devices.
To ensure that your podcast sounds great on various mobile devices, aim for a maximum peak level of around -7dB TP (to prevent clipping) and an average Loudness Units relative to Full Scale value of approximately -16LUFS – this will ensure it doesn’t become too loud once converted to MP3 format for distribution.
Podcast mastering involves reaching consistent levels across your podcasts to achieve this consistency, either manually or using an automated mastering service. A good automated mastering service will even out the audio, balance music and speech levels, reduce noise caused by fans, air conditioners or cars and eliminate volume fluctuations from episode to episode.

Do you Prefer Stereo or Mono Podcasts?

Podcasts can be an entertaining and educational way to communicate, but their production requires special consideration. Audio quality can make an immense difference between whether or not listeners enjoy your podcast; even small details like recording in stereo instead of using headphones could cause issues for listeners – and you may find out too late that many listeners find your show unpleasant!
Edison Research and Triton Digital conducted a report that indicates podcast listeners tend to enjoy their experience. Over half (59%) reported spending over five hours per week listening to podcasts – not only that but many different shows are tuned into.
Some of the most popular genres of podcasts include news and education, self-help/relationship advice, comedy and sports and recreation. There are also other categories for categorizing podcasts – for example u/mgdell reports that around three in ten podcast listeners claim an interest in true crime stories and self-help advice.
Podcast listening has many other uses as well, such as keeping up on current events, receiving encouragement and inspiration, or learning something new. No matter the purpose, most listeners spend about four minutes each day tuning in.

Are Fast Download Speeds Essential?

Since their introduction in 2004, podcasts have taken off like wildfire in digital media. Offering listeners an on-demand alternative to radio shows and giving them control over which topics interest them, many podcasts are produced not by big TV or radio companies but by small independent producers wanting to share their passion with the world – often hosted on their host’s website where users can leave comments or interact with both host and listener community members.
Users have adjusted to podcast listening habits over time, which makes understanding how your show is downloaded and played important for its effectiveness. For example, podcasts recorded in stereo consume more bandwidth compared to mono versions; this can be particularly relevant on mobile devices where storage and download speed may be an issue.
If your podcast will primarily consist of voice recordings or people talking, mono should be your go-to format. File size will be smaller, and listeners should find that mono audio sounds just as good if not better to them. Of course, you can still have music at the beginning or end of episodes; but for maximum effectiveness use mono.
Mono encoding settings will help keep file sizes down, making them easier for listeners and downloaders. They are particularly beneficial on mobile devices with limited storage capacities or bandwidth restrictions – for instance an iPhone’s 3G download limit is 20 MB while raw stereo files could take up over 620 MB! Podcasters should carefully consider their source audio before choosing either a bit rate or an encoding method.

Do You Really Need Expensive Headphones?

A pair of quality headphones is indispensable when podcasting. Not only can they enable you to monitor the audio while recording, but they also provide an idea of what it will sound like to listeners, as well as allow for small adjustments that could improve its final quality.
For recording purposes, headphones with closed backs that reduce sound leakage are best. This will give an accurate representation of your voice and limit any external noise that might otherwise enter through microphone(s). Aim for flat frequency responses without significant bass or treble shifts for optimal results. Comfortability should also be at the top of your mind since you will likely be wearing these for several hours during the recording process.
Finding headphones that meet both your budget and needs can be challenging, so choose ones that suit both. Think about impedance/device compatibility, frequency response, bleed/spill and impedance/device compatibility when making this selection; choose ones compatible with any audio devices (mobile phone or Apple headphone jack) on which you plan to record audio.
Mono is often preferred when creating spoken-word podcasts, particularly long episodes, as this will produce higher-quality audio files with reduced download sizes. Stereo may work well when featuring music or needs a “surrounding” soundscape; however, its larger file sizes result in less-than-ideal quality compared to mono files. As such, many podcasters will opt for mono for host and guest tracks while stereo for music tracks (when exporting to stereo be sure to set panning center so both channels have equal volume).
