Q: I’ve made a bunch of recordings of interviews in Russia that the producer wants to have translated with time code. Unfortunately no one is familiar with broadcast wave audio files. I have found a program called Audacity, but it doesn’t read the time code. (more…)
Analog Inputs 1 and 2 can be linked as a stereo pair, either L/R or MS. This allows control of the stereo pair with a single control. (more…)
Q: Are your files compatible with Avid and Final Cut Pro and do you need an audio program to open them on a Mac? (more…)
Q: I’m a blind technician. Most digital recorders can’t be used by people with a visually handicap. The design of the buttons on the recorders is really wonderful and made for tactile use. (more…)
Q: While recording some foley FX with sharp transients, even with the limiter engaged I was still hitting getting close to 0 dBFS. I was under the impression that the limiter threshold was -6 dBFS (according to the manual). What am I seeing? (more…)
Sound Devices’ word clock connections on 7-Series recorders do not have a 75 ohm terminating impedance. We do this because several units can be connected without over-loading the unit driving it. In most situations, using no termination works just fine. (more…)
Q: I have a 722. I also have a Canon XL2. Am wondering if purchasing the Horita PTG (SMPTE Time Code generator) could make the XL-2 be the master and the 722 a slave? PTG takes the composite video signal from my camera, and derives the time code for it. I am not sure if “word clock” is compatible with SMPTE time code? (more…)
The 7-Series recorders can record to several different file formats to extend record time and reduce file size. A review of the options are discussed in this article. (more…)
Many test and measurement applications take advantage of the impressive bandwidth offered by the 722 and 744T analog inputs. Linear frequency response, particularly low frequency response, is needed for noise and vibration measurements. Linear high frequency response is useful when slowing audio in post production. (more…)
Time code generated in file-based recorders is fundamentally different than time code on a tape recorder. Whereas a tape recorder has a continuous time code reference for each location on the tape, a (broadcast wave) audio file only has a single time code value—from which all time code values are calculated. (more…)
The hard drive generates nearly imperceptible noise levels, and it is the only device with any acoustical noise output on the recorder - no cooling fans, etc. Unless you press your ear against the unit you won’t be able to hear the drive during operation. (more…)
Q: We purchased two 744Ts, and we’re trying to figure out the best way to get the audio off of the internal hard drive. We’re currently running audio workstations on Macs with OS 9 installed. Is there a way to mount the 744T when attached via FireWire to a Mac with the OS9 operating system? (more…)
Question:
Is there, or will there be a possibility to upgrade the 722 to time code in the future?
Answer:
It is not possibility to upgrade the 702 or 722 to include time code. They have unique circuit boards. If time code is a required feature, consider the 702T or 744T, which include time code.
24 bit /192 kHz sampling looks impressive as a specification. Manufacturers offer these “marketing specs” for consumers to gobble up. In practice, the analog circuitry ahead of the conversion and storage system is the defining factor of a digital system’s performance. The fact that a device is 24 bit doesn’t have much to do with its audio performance. Leaving this fact aside, let’s look at what 24 bit recording can do in real world environments with high performance gear… (more…)
7-Series recorders running firmware later than 2.15 can play back MP2, MP3, and FLAC formatted sound files. These formats are in addition to the uncompressed, PCM WAV file formats available.
