In the early 2000s, mobile music production began with simple recording apps like Tascam Portastudio and Korg M1. These apps allowed users to record and playback audio, but were limited in terms of features and functionality. For example, Tascam Portastudio, released in 2005, allowed users to record up to 4 tracks of audio, with a sampling rate of 44.1 kHz and a bit depth of 16-bit. Similarly, Korg M1, released in 2004, offered a 16-track recording capability, with a sampling rate of 44.1 kHz and a bit depth of 16-bit.
