We recommend you master your audio files before uploading them to Simplecast. If encoded as an 128kbps or less MP3, we will not re-encode or transcode the audio. Programs like Apple Podcasts, Logic, or Audacity are able to master MP3s.
Great for spoken-word podcasts, especially those with long episodes. Quality will be good and downloads will be quick due to a smaller file size.
Also a great option for spoken-word podcasts, though downloads will be slower. Audio quality will be improved.
A good option if you need a stereo mix. Though due to how MP3s are encoded, you'll have 2 channels of 48kbps audio instead of one at 96kbps. File size will be similar to 96kbps/mono.
A great option for shows with music if you need a stereo mix.
Embedding ID3 Tags
It's always good practice to embed episode information directly into your MP3's ID3 tags. This will ensure that episodes display correctly in all podcast player apps including Apple Podcasts. Apple Podcasts is capable of embedding ID3 information into MP3s, including podcast artwork. We recommend an artist name, album name, track name, publishing year, track number, a genre of 'Podcast', and artwork.
