Pro tools delay compensation full#
Rich Tozzoli's book is an excellent handbook for anyone wanting work in surround with Pro Tools, whether for music, broadcast or film, and is full of pictures, screenshots and practical examples of real projects to help you to get stuck in very quickly. You'll need to mute the tracks you're recording on in Pro Tools, otherwise you'll hear both the direct signal and the delayed signal as recorded into Pro Tools.īook Review: Pro Tools Surround Sound Mixing The Mix knob on the front of the M Box or M Box 2 enables you to adjust the balance of direct input signal to playback signals from Pro Tools. The M Box and M Box 2, meanwhile, enable you to monitor the input signals directly whilst recording, so you can hear them without any latency. Also, it doesn't work via the digital outputs, so you can't monitor via the digital outputs while recording in the low-latency monitoring mode. Only analogue outputs 1/2 are available in low-latency monitoring mode, which is why Pro Tools muted my headphone feed on the session I was describing. All plug-ins on any record-enabled track are bypassed in Low Latency mode, and any record-enabled tracks will not register on the master meters. If you do a Bounce to Disk whilst Low Latency mode is enabled then any aux and Instrument tracks will be ignored and so won't feature in that bounce. When Low Latency mode is enabled, it will only work on tracks that have an input routed direct from an interface input, and not for tracks routed via an aux track, for example. This can be found at the bottom of the Options menu on Pro Tools 7 LE. The 002 and 002R offer buffer sizes down to 64 samples.With the 002 and 002R interfaces, however, Pro Tools LE offers a Low Latency mode. The amount of latency is related to the H/W Buffer Size: the larger the buffer size, the longer the delay. Pro Tool LE uses the processor in the computer for all audio processing, playback and recording, and to make it work reliably, audio data needs to be buffered on the way in and the way out, imposing a small amount of audio delay, or latency, in the system. So I looked into what was going on and workarounds to keep the session going smoothly, and I thought I would share the results of my investigations with you this month. I was feeding the performer's headphones from an aux buss and hadn't noticed that in Low Latency mode, Pro Tools mutes the aux sends of any track in Record I didn't become aware of this until later on in the session, when another performer complained they couldn't hear themselves. The singer was having some tuning difficulties, so I put Pro Tools into Low Latency Monitoring mode - and hey presto, the vocalist could sing in tune again. I knew that there were some latency issues with LE systems, and sure enough, when we came to the first overdub there were problems. With the 002 and 002R, Pro Tools LE offers a special Low Latency Monitoring mode.

With us flying out, taking my HD system was not a practical solution, but I have an 002R with a Focusrite Octopre in a 3U soft case, and together with some other bits and pieces loaded into my suitcase, I just got it within the 32kg single item limit. Often, these are used for broadcast production, and latency issues don't usually rear their ugly heads when using Pro Tools in this way, but recently I was asked by one of my clients to fly out to Northern Ireland to track and overdub some music tracks in a studio overlooking Carlingford Lough near Newry. However, I also do a lot of work on LE systems as these are what many of my clients have. When working on music projects I normally use my main Pro Tools system, which is an HD2 Accel system with a 192 I/O interface. So what's the best way to deal with this problem if you have only an LE system? One of the best features of TDM-based Pro Tools systems is the negligible latency, or input-to-output delay, while recording.
