A TASCAM trademark, "portastudio" is commonly used to refer to any self-contained multitrack recorder dedicated to music production.
[10] In 1982, TASCAM replaced the 144 with the 244 Portastudio, which improved upon the previous design with overall better sound quality and more features, including: parametric EQ, dbx Type II noise reduction, and the ability to record up to four tracks simultaneously.
[11][12][10] TASCAM continued to develop and release cassette-based portastudio models with different features until 2001,[13] including the "Ministudio" line of portastudios that offered a limited feature set and the ability to run on batteries at even more affordable price points, and the "MIDIStudio" line which added MIDI functionality.
[19] Later Digital Portastudio models, some with the ability to record 24 or even 32 tracks, utilize CD-R, internal hard drives, or SD cards, and commonly include built-in DSP effects.
In 2006, the TEAC Portastudio was inducted into the TECnology Hall of Fame, an honor given to "products and innovations that have had an enduring impact on the development of audio technology.
