Air Recorder is an app that lets you enjoy high-quality recording with easy operation. You can record sound through the internal mic of your iPhone/iPod touch, or wirelessly make digital recordings of the sound from your Roland electronic musical instrument. You can also load songs from the music library of your iPhone and play them back while recording your instrument as you play along.
You can use the internal mic of your iPhone/iPod touch to record your instrumental performance or your band. You can also load and play back songs from the music library of the iPhone. During song playback, you can use convenient practicing functions such as speed/key adjustments and AB repeat.
You can use Air Recorder with a Roland electronic musical instrument that has wireless LAN functionality, and digitally record the sound of your instrument wirelessly. Songs loaded from the music library of your iPhone can also be sent wirelessly and digitally to your instrument; you can then play along with the song on your instrument, and record the mix on your iPhone/iPod touch.
The recorded audio can be used via AudioCopy with any app that supports AudioPaste (e.g., GarageBand). You can also use Open in… to export the audio to another app that supports WAV or AAC file formats.
