What you need to edit a podcast

You need three things: recording software, editing software, and a place to store your files. Most people record directly into their editing software, so you may only need one program. The most common free option is Audacity, which records and edits audio on Windows, Mac, and Linux. If you want something simpler, GarageBand comes free on Mac and does both recording and basic editing. On Windows, Cakewalk by BandLab is free and handles both tasks as well.

For storage, you need enough disk space for your raw files — a one-hour podcast in high quality takes roughly 600 megabytes to 1 gigabyte. Most laptops have this, but if you record many episodes, consider an external hard drive. You do not need to buy anything; free cloud storage like Google Drive or Dropbox works fine for backups.

A microphone helps, but your computer's built-in microphone works for starting out. If you want to upgrade later, a USB microphone like the Audio-Technica AT2020USB or Blue Yeti costs between $50 and $150 and plugs directly into your computer.

Key Takeaways

  • Audacity is free, works on all operating systems, and handles both recording and editing in one program.
  • The basic editing workflow is: record, remove silence and background noise, cut out mistakes or dead air, add intro and outro music, then export as an MP3.
  • Most podcast hosting sites accept MP3 files and handle distribution to Spotify, Apple Podcasts, and other platforms automatically.
  • You can edit as you go (pause and fix mistakes during recording) or edit after (record everything, then clean it up later).
  • Exporting as MP3 at 128 kilobits per second is the standard for podcasts and keeps file sizes manageable.

Recording your podcast in Audacity

Open Audacity and check that your microphone is selected in the dropdown menu at the top left. Click the red record button to start. Speak naturally — do not worry about mistakes yet, you will fix them in editing. When you are done, click the stop button (the yellow square).

If you are recording multiple people, use a separate microphone for each person if possible, or record them on different tracks by having one person speak while you record, then recording the second person on a new track afterward. To add a new track, go to Tracks menu and select New > Stereo Track or Mono Track. This makes it easier to adjust each voice separately later.

Removing background noise and silence

Background noise — hum from your computer, traffic outside, keyboard clicks — is the most common problem in home recordings. Select all your audio by pressing Ctrl+A (or Cmd+A on Mac). Go to the Effect menu and choose Noise Reduction. Click Get Noise Profile, then apply it. This removes constant background hum. Do not overdo it or voices sound robotic.

Next, remove long stretches of silence. Select the silent parts (click and drag across them) and press Delete. This tightens the pacing and reduces file size. Leave short pauses between thoughts — they sound natural. Remove only the dead air where nothing is happening.

If you have a guest or co-host, use the Normalize effect to make both voices roughly the same volume. Select all audio, go to Effect > Normalize, and click OK. This prevents listeners from turning the volume up for one person and down for another.

Cutting mistakes and editing sections

Listen through your recording and mark spots where you want to cut. You can pause and use the Selection Tool (the I-beam cursor at the top left) to click and drag across the part you want to remove. Press Delete to cut it out. Audacity automatically closes the gap.

If you flubbed a sentence but want to keep the take, you can cut just that phrase and let the surrounding audio flow together. Be careful — if you cut mid-word, it will sound jarring. Cut at natural pauses instead. You can also use the Envelope Tool (the curve icon in the toolbar) to fade audio in or out smoothly rather than cutting it abruptly.

For longer edits, like removing a whole tangent or false start, select the section and delete it. Listen to the join point to make sure the audio flows naturally. If there is an awkward pause or volume shift at the edit, use Normalize again on just that section to smooth it.

Adding intro and outro music

Most podcasts open with a short music clip (10 to 30 seconds) and close with another. You can find royalty-free music on sites like Epidemic Sound, Artlist, or YouTube Audio Library. Download a track as an MP3 file.

In Audacity, go to File > Import > Audio and select your intro music file. It will appear as a new track above your voice. Drag it to the beginning of your timeline. Use the Selection Tool to trim it to the length you want — usually 10 to 20 seconds. Lower its volume so it does not overpower your voice by selecting it and going to Effect > Normalize, then lowering the volume slider to around -3 to -6 decibels.

Do the same for your outro music at the end. Make sure the intro fades out smoothly into your voice and the outro fades in after your last words. You can use the Fade In and Fade Out effects (Effect menu) to make these transitions sound polished.

Exporting your podcast as an MP3

When editing is done, go to File > Export > Export as MP3. Audacity will ask you to download the MP3 encoder if you have not already — follow the prompt. Choose a filename that includes the episode number or date, like "Episode_001.mp3" or "Podcast_Jan_15.mp3".

In the export options, set the bitrate to 128 kbps (kilobits per second). This is the standard for podcasts — it sounds good and keeps file sizes around 10 to 15 megabytes per hour. Higher bitrates make larger files with no noticeable quality gain for speech. Lower bitrates (below 96 kbps) start to sound thin.

Before you export, add metadata (title, artist name, episode description) by filling in the ID3 tags window that appears. This information shows up in podcast apps when listeners download your episode. Save the file to a folder where you keep all your episodes.

Uploading to a podcast host

You cannot upload directly to Spotify or Apple Podcasts. Instead, you upload to a podcast host — a service that stores your MP3 files and sends them to all the major platforms. Common hosts include Buzzsprout, Anchor (owned by Spotify), Podbean, and Transistor. Most have free tiers that let you host a few episodes.

Sign up, create a new podcast, and fill in your show title, description, and artwork (usually a square image at least 1400 by 1400 pixels). Upload your MP3 file and add episode details like the title and description. The host generates an RSS feed — a link that Spotify, Apple Podcasts, and other apps use to find your new episodes automatically.

Submit your RSS feed to each platform. Apple Podcasts, Spotify, and Google Podcasts all have submission pages where you paste your feed URL. It usually takes a few hours to a few days for your episode to appear.

Common editing mistakes to avoid

Do not over-edit. Removing every pause or breath makes speech sound unnatural and robotic. Leave some silence — it gives listeners time to absorb what you said. A one-second pause feels natural; a three-second pause feels awkward.

Do not max out the volume. If your audio is too loud, it distorts and sounds bad in podcast apps. Aim for peaks around -3 decibels. You can check this by looking at the waveform — if it is touching the top and bottom of the track, it is too loud.

Do not forget to save your Audacity project file (.aup3 format) before exporting. This lets you go back and make changes later without re-recording. Export as MP3 only when you are ready to upload.

Frequently Asked Questions

Can I edit a podcast on my phone?

Yes, but it is slower and harder than on a computer. Apps like Anchor and Podbean let you record and edit on your phone, but they have fewer editing tools. If you record on your phone, transfer the file to a computer and edit there for better results.

How long should a podcast episode be?

There is no set length. News and interview shows often run 30 to 60 minutes. Solo commentary shows run 10 to 20 minutes. Listeners will stick with whatever length you choose if the content is good. Start with what feels natural for your topic, not what you think you should do.

What if I want to add music or sound effects in the middle of an episode?

Import the audio file as a new track in Audacity, position it where you want it, and adjust its volume so it does not drown out your voice. Fade it in and out using the Fade In and Fade Out effects. Test it by playing back the section to make sure the timing feels right.

Do I need to edit every episode the same way?

No. Some episodes need more editing than others. If you recorded cleanly with no mistakes, you might only remove silence and add music. If you recorded with a guest and there were technical issues, you might spend more time on noise reduction and volume balancing. Adjust your process to what each episode needs.

What format should I use if I want to upload to YouTube as well?

Export as MP3 for podcast platforms and as WAV or MP4 for YouTube. YouTube accepts both audio and video files. If you want to upload video, you can pair your audio with a static image or simple animation. Most podcast hosts do not handle video, so you upload video separately to YouTube.
