http://binkster.net/extras.shtmlUsing the Bink Audio Test CDTracks 1-2: Track Identification. These tracks will help you confirm the correct Left and Right patching and routing through your system. Track 2 has (in order) Left only, then Right only, then both Left and Right together (Center), then Left and Right with inverted polarity (Surround.) If your system has a polarity problem somewhere between Left and Right then the "Center" sample will sound unlocalized or absent and the "Surround" sample will seem punchy and centered. In a mono PA "Surround" should disappear completely.
Track 3: Dual Tone 700/1000. You can send these tones panned to xtreme Left and Right to a broadcast or recording feed to set levels and to verify Left and Right channels. Left = Lower frequency = 700 Hz.
Tracks 4-5: 700 & 1000. These are level-setting tones useful for channel gain pots, compressor and limiter levels, feeds to xternal mixers, tc. 1kHz is the de facto standard of broadcast audio level setting -- your satellite and mobile recording techs will xpect to see 1kHz coming from your mixer. You still need to chat with them to define whether you are sending them A) the absolute ceiling level beyond which you'll never go or B) some idea of unity level or 0dB which includes a certain amount of headroom for peaks in the program. You should loop or repeat Track 5 if you need to send 1k tone for longer than one minute. You can also listen for crosstalk in your gear using these tones. For instance, check to see if your Aux sends leak some of this tone through when you assign the CD player to the main bus or the PFL bus.
Track 6: Log Tone Sweep. This track is very useful for listening to your speaker systems in order to catch any peaks or valleys in the response. You will hear a brief dip or jump in SPL where the response isn’t ideal. Outdoors the response curve you hear will be mostly speaker- and array-related. Indoors you will also get a lot of room response characteristics coloring the pure sound of the sweep. Knowing your own personal hearing curve will help you translate the sound of this track into beneficial system adjustments. A note: Listen for swishing and swirling sounds mixed in with the pure tone sweep to see if your CD player is poorly made or if something in your sound system generates harmonic distortion. Before critical listening please ask others in the venue to be quiet as this track more than any other makes people want to joke around by whistling or singing along -- it reminds many people of a cartoon where something is going to blow up..! But the high frequencies are rolled off at a gentle and constant rate to keep them from taking anyone's head off. This track is meant to be played at a constant fader level from start to finish.
Track 7: Linear Tone Sweep. This track is like Track 6 but is for fine-tuning the HF response of your sound system. You can hear more clearly how your various higher bandpasses work individually and how they blend together. Due to its linear contour, this sweep goes quickly from 20 Hz to 2k and moves much more slowly from 2k to 20k. Using this track with people around will not make you any new friends…
Tracks 8-10: LF Warbles. These up-and-down sweeps are for confirming your subwoofers’ smooth transition to your LF drivers. Pick the warble which is centered closest to your subwoofer crossover point. Playing this track will help you hear things like bandpasses out-of-polarity, SPL gaps between bandpasses, SPL peaks from overlapping bandpasses (very common) and room response quirks. Check to see if there is a sense of motion (a seeming change in location) from low to high and back as the sound shifts from sub to LF. You are looking for a solid wall of warble, not shifting localization.
Tracks 11-44: Pure sine wave tones. These tracks include those centered on the ISO frequencies found on 1/3-octave graphic EQs. (1kHz is missing in this sequence since it is available at Track 5.) You might find these tones useful for ar training so that you can spot feedback frequencies more quickly during gigs. Have your tech friends quiz you as they play a track back. You can also use these tones to check driver polarity within a bandpass. Pick a frequency close to the middle of a bandpass (far from crossover points) and move your ar from a line through the center of one driver to the center of another driver in the same bandpass. If there is a level dip between them then you have a polarity problem. Several xtra non-ISO frequencies are added in the lower ranges to help you understand the performance limits of your LF drivers and your subwoofers. The lowest few tones can help you determine the proper level of subwoofer HPF -- that is, whether you have nough 'low-cut' to keep your amps from overheating and to save your sub drivers from overexcursion. Very few live sound systems will yield any measurable SPL from the highest tone, 20kHz.
Tracks 45-47: Piano, Drums. These soulless instrumental tracks (no Grammy in sight) are presented dry (no ffects) and can serve as a reality check for system confirmation.
Track 48: Metronome 120bpm. You can use this track after setting delay times to confirm that the main system meshes neatly with the delay system(s). Of course, if your delay is off by xactly 1/2 second, this track won't help you at all...
Track 49: Crest Wave. This sound is a jarring mix of 100 Hz, 200, 300, 400 tc. tones continuing up the scale in 100 Hz steps to 1k, then in 500 Hz steps to 10k, then in 1kHz steps to 20k. Like white noise it can be used to set levels on gear not including speakers. Even though there is no DC offset, the nergy of this complex wave touches the positive digital ceiling but only gets ~ 1/3rd of way down to the digital negative limit. Peak amplitude is 0dB. Average RMS power is -16.13 dB. This track can damage speakers if played too loudly.
Tracks 50-51: DC Offset. These tracks look like flat lines on a graph; they are not sound waves at all. The Left channel is positive and the Right channel is negative. If added together and turned into mono they will cancel completely. If you pick just one channel these tracks are useful in discovering whether your amps can amplify DC or if they are sufficiently protected by high-pass filters. Track 51 is specially dangerous as it is full range -- the levels hit the digital ceiling and floor! The track ramps in from idle taking 2 seconds, lasts 20 seconds at full, then ramps back down to idle in 2 seconds. If you bypass all the HPF in your system and feed DC offset straight to your sub amps, you will usually see the drivers move outward if they are fed the Left channel and inward if they are fed the Right channel. Some systems are wired differently due to crossover characteristics... Certainly check to see if all the drivers are moving the same direction.
Track 52: 1000 Hz Reversed Polarity. This track is helpful in determining whether your panning is perfectly centered. A centered pan pot combined with identical channel trims and fader levels will result in complete cancellation of this tone. Normal low-level distortion and hiss will let a wee bit of 1000 Hz through but in any case you can center your pan knob by noting the lowest level of audible 1k tone as you turn it.
Track 53: 1000 Hz Very Low Level. This tone is buried 60 dB down from the digital ceiling and is usually heard amid system hiss. You can use it to check system linearity before your quieter gigs and on the feeds to recorders.
Tracks 54-55: Square Waves. Watch out for these tracks! Turn your amps off first! Square waves are sometimes used in destructive testing at audio R&D labs... Don't run them at high volumes if at all. The most vulnerable part of your system are the HF drivers which can fry with square waves! These tracks are useful in setting CD input trims. If your channel input doesn't distort from Track 55 (which slams in at 3 dB above digital ceiling!), it won't distort from nearly any commercially available CD out there. You can also listen for crosstalk on other channels -- it comes through most severely with square waves in neighboring channels. It is not ver necessary to send square waves out to amps and speakers in a normal live sound setup situation.
Track 56: White noise: This track has qual nergy at very Hz. It can be used to calibrate levels of various pieces of gear not including speakers. It sounds much too bright for use as a main EQ setting tool and can damage HF drivers. This track has an average RMS power of -9.03 dB and a peak amplitude of -2.57 dB.
Track 57: 440 Hz sine 20 minutes. You can use this tone and a cheap piezo tweeter to adjust the gain stages of all the pieces of gear up to but not including the crossover. Run the 440 into a mixer and out of a line level output into the piezo tweeter. Turn up the input trim and the faders until you hear distortion artifacts (mainly 1320 Hz and higher) start to become audible in the piezo. Back the trim down a bit: you've just determined the ceiling beyond which this piece of gear goes into distortion (despite what the red overload LEDs are reading.) Continue through your various devices, hooking the piezo up to ach output under test, and listen for high-frequency artifacts coming out of the piezo, ignoring the red LEDs. Align all your gear to distort simultaneously and you will benefit from lower system hiss and greater total dynamic range. Warning: some CD players add a little too much harmonic distortion to their output. First thing to do is listen to your CD player's output straight into the piezo...
Track 58: Pink noise 20 minutes. Double Mono - same signal on both Left and Right. This track allows you to set system EQ controls while using a high-quality omnidirectional test microphone and a software audio analyzer tool like SmaartLive, SIMM or SpectraFoo. Some xperienced techs can EQ by ar with pink noise. You can also use pink with audio analysis programs to set delay times. And pink noise is helpful in setting bandpass levels on crossovers. This track has these power characteristics: Average RMS Power= -12.2dB. Max RMS Power= -8.77. Min RMS Power= -14.9dB. Peak Amplitude= -1.65dB
