Version 1.5 also adds a horizontal bar graph meter to the main display. Users can now view current, max, and peak sound levels simultaneously, both in the text display as well as in the new bar meter. As a result, SoundMeter's controls have been simplified, without sacrificing any flexibility. A new Options screen enables the user to disable automatic inclusion of date and time or location information.
SoundMeter is compatible with all versions of the iPhone and iPod touch. iPod touch users will need external hardware for use with SoundMeter, and will not be able to take photos, due to the lack of a built-in camera. Users may visit Faber Acoustical online for information regarding audio input options for iPod touch devices.
