The higher the accuracy, the more of the CPU’s capacity is used and the longer the latency (as opposed to the audio buffer size settings). In order to eliminate unnecessary background noises, select the appropriate value.Ģ dashes (default) – the best compromise between accuracy and latency. Based on autocorrelation, the beat bars proprietary methodĪ2M works best when it only recognizes sounds at an appropriate volume level.The smaller the buffer, the higher the CPU load and the lower the latency.Ī buffer less than 512 should only be set if you have a strong processor.įor A2M standalone applications, the buffer size is available in the application settings under Audio Settings → Buffer Size The list of active and inactive MIDI ports is available in the application settings in the MIDI Settings → Outputs section.Ī2M works (though imperfectly) as an AU plugin in Logic Pro (see user guide).Ī2M does not work as an AU plugin in GarageBand. The app sends MIDI events via the virtual MIDI port. The standalone version works with all MIDI-compatible applications, including GarageBand and Logic Pro. On the other hand, it generates output MIDI events, just like any MIDI effect. On the one hand, it analyzes the input sound, just like any audio effect.

Due to its characteristics, it is something in between. The A2M is quite an unusual Audio Unit – it is both an audio effect and a MIDI effect. These acoustic (or electric) instruments, or your voice, act as a MIDI controller.Ī2M comes as an AUv3 plugin and as a standalone application (which is the AU host for this particular plugin). Thanks to this, you can play, e.g., the guitar, saxophone, or even sing, and simultaneously trigger sounds in virtual instruments (not only AU).

Just play an instrument or hum and turn the melody into an instrument of your choice.Ī2M detects the pitch of the audio and converts it into the corresponding MIDI notes in real time. Convert your audio source directly to MIDI.
