Features

 

Save time

The last thing podcast producers need is more tedious, manual steps to publish each episode. Forecast automates common workflows and saves time even if you never use chapters. And if you want to add chapters, it has never been easier.

 

Autofill

Forecast embeds artwork, title, and description in each MP3. (No more editing in iTunes!)

 

Name your input files with the same prefix and numbering system each time, e.g. “atp100.wav”, “atp101.wav”, etc., and Forecast will automatically fill in the title, artwork, and episode number.

 

Forecast also remembers and autofills the most recently used URL and/or image for each chapter title, saving you a bit of time if you have some repeating chapters over multiple episodes or between multiple shows (sponsors, bumpers, etc.).

 

MP3 Chapters

Add chapters to make it easier for listeners to navigate your podcasts. Forecast reads and writes the MP3 Chapters standard, with full support for embedding titles, link URLs, and images.

 

Even if structured chapters aren’t for you, if you’d like to show the listeners what you’re talking about at a certain time, you can also add special chapters that don’t display in the chapter list (in supported podcast players) — they simply show a link or image to the listener at a relevant time, for whatever duration you’d like.

 

Import markers as chapters

There’s no need to manually create chapters in Forecast. Simply create markers in your audio editor as you edit your podcast, export it as a .WAV file to Forecast, and Forecast imports each marker as a chapter.

 

Fast, high-quality MP3 encoder

Even Forecast’s MP3 encoder is designed to save you time. It’s the world-class LAME MP3 encoder, but custom-integrated to spread the work across all of your processor’s cores, saving time by using your computer’s full potential.

 

Silence warnings

Forecast will warn you if the input file has a long span of silence that’s likely to be unintentional, saving you the embarrassment and hassle of a bad file before it gets to your listeners.

 

Quick-copy duration and file size

Simply click the duration or file-size buttons on top to copy their values for pasting into your podcast’s CMS or host. (Save even more time with a clipboard manager.)

 

Export sponsor airchecks

If you mark your sponsor breaks with chapters, Forecast can export “airchecks” for sponsors (the sponsor breaks, cut out as their own files) with one click in the File menu.

 

Battle-tested by pro podcasters

Forecast-encoded podcasts have already been served to many millions of listeners over its two-year private beta test. Now, it’s finally available to everyone.

 

And it’s free!

Forecast is free.

 

There’s no catch, no creepy business model, and no ulterior motive.

 

NOTE: Forecast is still a beta. It has been tested and used in production for two years, but the interface is still a bit rough. Feedback is welcome in the Overcast Slack group.
