2. Highest quality
With Spire Studio, you can also share your song in highest-quality audio. Selecting the Highest quality option will allow you to send somebody an audio file in WAV format. Your song will be shared as the highest fidelity audio at 44.1 kHz and 24-bit depth.
Unlike compressed M4A files, which will weigh around 1 MB per minute of music, WAV files are uncompressed, so they’ll take up around 10 MB per minute of music. You can see that a 4-minute song will quickly add up to 40 MB, which is why these files aren't meant to be shared via text or email. Instead, use services like Dropbox, iCloud Drive, or Google Drive to share these files.
To send your song as an uncompressed high-quality audio file, follow these steps:
1. Tap the Highest quality option, which will bring up the iOS Share Sheet
2. Choose to share your audio file via Dropbox, iCloud Drive, Box, or any other file sharing service. Your options will vary depending on the apps you have installed on your phone
