Most popular recording apps will have two settings that will have an effect on the latency – i.e the time it takes for the incoming audio signal from the iTrack One Pre to pass into your iOS device > into the recording app and back out via the speaker or headphones.
These two settings are:
- Whilst 44.1kHz and 48kHz tend to be the most common sample rates audio is recorded at, the iTrack One Pre can record at the following sample rates; 44.1 kHz / 48 kHz / 88.2 kHz / 96 kHz.
Many recording apps also support recording at sample rates up to 96kHz. Typically, recording at higher sample rates will result in lower latency but create much larger audio files. We recommend using 44.1kHz / 48kHz in almost all cases.
- This value determines how much time is allocated to deal with the incoming/outgoing audio. Therefore, lower buffer sizes allow less time, resulting in lower latency. Higher buffer sizes allow more time, and so will increase the time it takes for the audio to pass into and out of the setup.
