'All of the CDs we've seen suffer from the same fatal problem.' 'Note the peak/dip pair at 110 and 122 Hz where the response varies a staggering 32 dB across a range smaller than one musical whole step.' 'To solve this problem we created a series of MP3 files you can download and burn.' 'Be careful not to make any noise yourself, or tap your foot, or breath loudly near the microphone capsule.' | Download the RealTraps Test Tone CD Zip file HERE (3.2 MB). Note that these tones measure raw low frequency response only, and are meant for use only when it's not practical to connect a computer to your audio system. These tones do not identify modal ringing or other time-based errors which are just as important. But they will give you an accurate assessment of the low frequency response of your loudspeakers in your room. For more thorough room testing we recommend the freeware Room EQ Wizard, or ETF and R+D programs for Windows from Acoustisoft. For Mac users we suggest FuzzMeasure. Our Room Measuring Primer explains how to use room measuring software. OVERVIEW There are a lot of commercial test tone CDs available, but all of the CDs we've seen suffer from the same fatal problem: The tones are spaced at either 1/3 or 1/6 octave intervals, which is far too coarse to assess the low frequency response in rooms the size you'll find in most homes. The graph below shows the response at the listening position in a typical 16 by 10 by 7-1/2 foot room. Note the peak/dip pair at 110 and 122 Hz where the response varies a staggering 32 dB across a range smaller than one musical whole step. This behavior is completely hidden when measured at 1/3 or even 1/6 octave spacing. To solve this problem we created a series of MP3 files you can download and burn to a CD. Our intent is not to duplicate all of the features of commercial test CDs. Therefore, we supply only low frequency sine waves, in 1 Hz increments, with a track organization that's easy to understand. We also created a blank sheet of logarithmic graph paper you can print to plot the results. Top You can use any inexpensive Sound Pressure Level (SPL) meter such as those sold by Radio Shack. Simply place the meter where your ears are when seated in the listening position, play the CD, and write down each number displayed by the meter. Each tone is ten seconds long, which gives you enough time to switch the meter range when needed. Yes, it will take the better part of an hour to run these tests, but when you're done you'll know your room's true low frequency response. Some test CDs 'calibrate' the level of each tone to match the known inaccuracies of the Radio Shack SPL meter, but we didn't do that for two reasons. First, meter calibration offsets are not that useful because all Radio Shack meters are not the same. More to the point, low frequencies are usually accurate enough even with inexpensive microphones. We compared our Radio Shack SPL meter to our own expensive AKG calibrated microphone, and they were within 1 dB of each other below 600 Hz. The main point of these tones is to find the major peaks and nulls at low frequencies, and any inexpensive meter is fine for that, calibrated or not. Top Note that the playback volume must be set high enough for the tones to be well above the ambient noise in your room. If you have nulls that are 30 dB deep - which is common - the tone must be at least 30 dB louder than the ambient noise in order to measure the full extent of the nulls. Track 30 contains 15 seconds of pink noise which you'll play before running the sine wave tests to ensure an adequate signal level. Play Track 30 and set your receiver's volume so the SPL meter reads about 70 dB before running the tests. Also be sure the meter is set to use 'C' weighting (the default), which is needed when measuring low frequency response. If the level at low frequencies is so high you hear obvious distortion, then run the tests again at a lower level. Likewise, if all of the tones seem fairly soft, you'll need to raise the overall level. Common sense will tell you when you're within a useable range. You may find that some low frequency tones cause windows and furnishings in the room to vibrate and rattle, so you'll need to fix those before you can measure the low frequency response accurately. Also, be sure there are no other noises present when running the test, such as the rumbling of a furnace or air conditioner. Likewise, be careful not to make any noise yourself, or tap your foot, or breath loudly near the microphone capsule, while reading the meter levels. The tones are spaced at 1 Hz intervals, with ten tones per CD track, and the layout is shown below under Track Contents. At most frequencies you can hear the transition from one tone to the next, but you can also use the CD player's time readout if needed. For example, Track 10 plays 100 through 109 Hz, so if the time readout says 23 seconds that means you're 3 seconds into the 102 Hz tone. If you get lost, just rewind to the start of the current track and resume from there. The close 1 Hz spacing also makes it difficult to squeeze that many tiny dots onto the graph paper at the upper end of the range, above about 100 Hz. So just plot all ten tones for each track in the same space, one on top of the other, and the peaks and dips will still reveal themselves clearly. Top USING THE FILES All of the files needed are in the test-cd.zip file you can download at the top of this page, and they are named numerically to end up on the CD in the proper order automatically. Simply extract all of the files to a folder on your hard drive, then drag the files as a group to your CD burning program to create an audio (not data) CD. You can sort the list of file names alphabetically, if needed, before dragging the files. You can also print the accompanying Test Graph.gif file to plot the results. If you have a graphics program, print the image from there and tell the program to fill the page when printing. TRACK CONTENTS (All tracks are recorded at -1 dB.) Track 1: 10-19 Hz in 1 Hz increments. Track 2: 20-29 Hz in 1 Hz increments. Track 3: 30-39 Hz in 1 Hz increments. Track 4: 40-49 Hz in 1 Hz increments. .. Track 29: 290-300 Hz in 1 Hz increments. Track 30: Wide band pink noise Wave file, 15 seconds, for setting the level to about 70 dB for the subsequent tests. Top |

As reviewers, we rely on lab tests (at least in part) to evaluate gear, but we rely a lot more on our collection of stereo test tracks, which have been accumulated, augmented, and pruned through years of testing experience. Most of these tunes are stored on computers as WAV files, on mobile devices as MP3 files, and on numerous CDs. These songs are the kind that we can play through speakers or headphones in order to quickly assess how well (or not) a product sounds.
Any audio enthusiast should put together a selection of tunes like this. It's convenient for checking out pairs of headphones in stores, a friend's new stereo speakers, or the audio systems you might encounter at Hi-Fi shows. You can even edit the songs if you like, cutting straight to the parts you want to hear just for testing purposes. There are a number of sound-editing software tools available as free downloads for mobile devices and computers.
In order to get the best possible fidelity from songs, be sure to buy the CD (it's also possible to digitize vinyl LPS) in order to create lossless digital music files. Or, at the very least, download the highest-quality MP3 tracks available (recommended 256 kbps or better).
Take note that your audio test tracklist can evolve over time, but you should have several staple tracks that you know well and do not change. The folks at Harman Research, who easily rank among the top audio researchers in the world, have been using Tracy Chapman's 'Fast Car' and Steely Dan's 'Cousin Dupree' for over 20 years now.
Toto, 'Rosanna'
This has become the first test song we usually put on. Scoff if you will at Toto's album, 'Toto IV,' but this track's dense mix truly spans the audio spectrum. This is usually the quickest test we've found for judging the accuracy of an audio product's tonal balance—the relative level of bass to midrange to treble. Just 30 seconds of 'Rosanna' will tell you whether a product is on the good or bad side of things.
We used to use Steely Dan's 'Aja' for this purpose, and this track is still a good choice.
Holly Cole, 'Train Song'
We purchased Cole's album, 'Temptation,' when it was first released back in 1995. Ever since then, 'Train Song' has been one of the first three test tracks played when we evaluate an audio system. This song starts with some intensely deep bass notes, which can easily push lesser speakers and subwoofers towards distorting the lows.
The tinkly percussion that dances across the front of the soundstage is a great test of high-frequency performance and stereo imaging. If your tweeter can cleanly and clearly reproduce the super high-pitched chime, struck right after Cole sings the line, '…never, never, never ring a bell,' then you've got a good one. Be sure to go with the studio recording over the live version.
Mötley Crüe, 'Kickstart My Heart'
This tune from the Mötley Crüe album, 'Dr. Feelgood,' uses so much dynamic compression that the readout on your sound pressure level meter (or the needle on your amp's output meter) will barely move. And that's a good thing because the steady level lets one judge the maximum output capabilities for products like Bluetooth speakers and soundbars.
But listen for the way your system reproduces the bass and kick drum during this song; the groove should sound punchy, not loose, bloated, or boomy. Sadly, many headphones make this tune sound boomy, and that is just plain wrong.
The Coryells, 'Sentenza del Cuore – Allegro'
'The Coryells,' the eponymous album featuring jazz guitarist Larry Coryell and his hyper-talented sons Julian and Murali, is one of the best that Chesky Records has ever done—and that's saying a lot. This particular song is a favorite for judging soundstage depth.
Listen for the castanets in the recording, as they are key. If the instruments sound like they're coming from 20 or 30 feet behind the guitars, and if you can hear them echoing off the walls and ceiling of the large church where this recording was made, then your system is doing a fine job.
World Saxophone Quartet, 'The Holy Men'
'Metamorphosis' is a great album by the World Saxophone Quartet, and 'The Holy Men' is one of the best test tracks for stereo imaging and midrange detail that we know of. Each of the group's four saxophones—all four of which play nonstop through the entire tune—is positioned at a certain place within the stereo soundstage.
You'll want to be able to pick out each saxophone individually and point to it (yes, in the air). If you can do that, then you've got a fantastic system. If not, don't worry too much, because this particular listening test is pretty hard!
Olive, 'Falling'
If you want one of the best bass tests in existence, go for Olive's 'Extra Virgin.' We often use the song 'Falling' when testing for the best subwoofer placement. The synthesizer bass line is powerful and punchy, dropping way down to a deep note, one that tends to nearly disappear when played over mini speakers or bad headphones.
Know that this is a harsh-sounding recording if you're listening to the mids and treble. So it might be worth making a custom version with the treble rolled off -6 dB at 20 kHz.

Wale, 'Love/Hate Thing'
Headphones can sometimes be marketed as a 'hip-hop thing,' with many popular models designed specifically with hip-hop in mind. In our opinion, most hip-hop mixes are too elemental to tell you much about an audio product. However, rapper Wale and singer Sam Dew are an exception with the song, 'Love/Hate Thing' off the album, 'The Gifted.' Both of these men have smooth voices that shouldn't sound rough on any good system.
But the best part of this track is the background vocals repeating the phrase, 'Keep giving me love.' Through a good set of headphones or speakers, these vocals should sound like they're coming at you to the sides (45-degree angles) and from a long distance. You should feel some tingles along the spine or prickles on the skin. If not, a new set of headphones might be in order.
Saint-Saëns’ Symphony No. 3, 'Organ Symphony'
This may be the best deep-bass test ever. We don't mean the booming, headache-inducing hip-hop or heavy rock brand of bass. We're talking about the subtle, beautiful bass emitted by a massive pipe organ, with its deepest notes reaching way down to 16 Hz. This recording from Boston Audio Society's album 'Test CD-1' is not to be played without caution.
Be aware that the low tones are in this track are so intense that they can easily destroy small woofers!
You'll want to enjoy it through some monster subs, such as the SVS PB13-Ultra or the Hsu Research VTF-15H. This track is absolutely spectacular and something that any self-respecting audiophile or audio enthusiast should appreciate and own.
Trilok Gurtu, 'Once I Wished a Tree Upside Down'
Ultra Bass Test Mp3 Download
There's no better way we've found to test stereo and envelopment than this cut by Indian percussionist Gurtu, with saxophonist Jan Garbarek. When listening to 'Once I Wished a Tree Upside Down' off the album, 'Living Magic,' pay attention to the chocalho shaker chimes.
If your speakers are top-notch, the sounds of chimes will seem to swirl around and even materialize right in front of you, almost as if Gurtu were standing between you and the speakers—and this isn't hyperbole! Put on a pair of the best electrostatic or planar magnetic headphones, and you can hear exactly what we're talking about.

Dennis and David Kamakahi, 'Ulili'E'
From the Kamakahis' album 'Ohana,' this is a gentle and lovely recording of slack key guitar and ukulele behind two rich male voices. Those who listen to this song through lesser sound systems may not be so impressed. If this is true, it can mean there's a problem with your speaker's upper-bass reproduction, or that your subwoofer's crossover point is inappropriate, and/or the positioning of your speakers and subwoofer needs adjustment.

Reverend Dennis's voice is especially deep, which can sound bloated on most systems. This recording—the detuned strings of the slack-key guitar in particular—should sound amazing. If it doesn't, then you've got some work to do to improve your system's audio performance.
