Brown Note Shepard Tone Illusion WarningLoud sounds can cause equipment/hearing damage with even a single, brief exposure. Always turn your audio system level down to a reasonable level, before playing our sound files.

When I play the same 7.1.4 Dolby Atmos test tones video (MP4 file with Dolby Digital Plus audio) from my iPhone (from Safari) via AirPlay to the Apple TV or Roku Ultra, the LFE channel only plays from the Sub while the Arc remains silent. This seems like how the LFE test tone is supposed to play rather than the result I get with the Blu-ray disc above.

So what exactly is happening here? When I play movies on Blu-ray disc in Dolby Atmos, everything seems to sound fine. Why is the pink noise playing on the Arc during the LFE channel test on the Dolby Atmos test tones Blu-ray disc?

If this is the case, why do the left front, right front, and center channel test tones play separately out of the proper drivers on the Arc? And how would this explain the same test tones video playing correctly via AirPlay to the Apple TV or Roku Ultra?

Here you can download four MP3 files that help you to evaluate the low frequency reproduction in your audio system. These signals are equally suitable for full-bandwidth monitors and subwoofer systems. The signal that contains only one frequency is called a tone.

First of the test signals boink.mp3 is a collection of tones at individual frequencies. Each of them is 10 cycles long. The frequencies in this signal are 16, 18, 20, 22, 26, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 120 and 150Hz. There is a little space between the tones to enable your audio system to build up its forces. As you play this signal pay attention to the purity of the tone. The tone should be clean and all tones should have the same level. If you hear any distortion, noises or rattling check your sound system and your room. The source may be your loudspeakers but also something resonating in your listening room or even the audio equipment feeding the loudspeakers. This signal is particularly useful for testing the output capacity of your system because the signal is not continuous, stressing your audio system similar to actual music and yet the signal is analytical and well defined. Start from a low sound level and work up towards higher levels. Notice any changes.

The second test tone sweep1.mp3 contains a tone that changes linearly in frequency from 10Hz to 150Hz. The level of the signal remains constant. Use this signal to check at what frequency the sound in your audio system becomes audible, how precisely the sound level remains constant over frequency and to locate any clear dips (anti-resonances) and peaks (resonances) in level at your listening location. Also you can locate problematic structures in your room, such as resonating curtain rails or furniture rattling at certain frequencies.

The third signal pink.mp3 contains noise. This 'Pink' noise has a particular characteristic (equal power per octave, power density decreases 3dB per octave) that makes all frequencies in the noise equally audible and therefore the pink noise can reveal very small frequency response differences effectively. It is an excellent signal for comparing the effect of any change you introduce in your sound system in the A/B test fashion. It has a spectrum similar to actual musical signal, and stresses your sound system similarly. Also, you can use this signal together with an octave-band or a third-octave-band real time analyzer to calibrate your sound system.

The fourth signal 85Hz_sinewave.mp3 contains a tone for adjusting the phase of a Genelec subwoofer. Some subwoofer models do not feature a built-in test tone generator, so an 85 Hz test tone is useful to help set the phase adjustment correctly. The instructions for its use can be found in the subwoofer operating manuals and Quick Setup Guide. This is a full scale signal, so please turn the volume down before starting the test.

Hi all. I recently got the RP-150Ms with the RP-250C. When running the test tone on my AVR, The left speaker sounds different than the right speaker, but the center sounds similar to the right speaker. how can this be?

If your left speaker and right speaker have dissimilar distances to sidewalls or are at different distances from the front wall, or there is a big difference in any acoustically reflective surfaces left-right, including coffee tables, racks, or big leather chairs, or ceiling height, you'll hear a timbre difference between left and right with test tones. Actually, this is the most sensitive listening test for this--using pink noise.

Sorry for being a little vague, I meant that the "timbre" is different between the left and right speakers when playing the test tone. I just swapped the L and R to see if it was room acoustics, and the issue remains...the timbre is still different with that speaker. I guess it could be an internal wiring issue .

I checked the internal wiring, and it all checks out...nothing wired out of phase and all connected securely. Hooked it back up and both drivers are working. I replayed the test tone and placed my ear close to both speakers, and up that close they sound "timbre" matched...so it must be room acoustics...??.

I am struggling with the same issues on some DIY speakers (DIYSoundgroup, Cheap Thrills. 15" woof, 12" SEOS waveguide w/ DNA 360 CD). One speaker is clearly not timbre matched with the other using the test tone from the AVR (not sure if it's pink or white noise.) One speaker is down about 3 db from the other, according to the AVR's Audyssey.

Windows 11 sound quit working. Hardware tests good -- speakers play tones. Software is broken following recent Windows Update. I have tried ALL Hp diagnostic tests and Microsoft's as well, including updating drivers, uninstalling device and letting reinstall, etc. I have run sfc /scannow with no issues. Every diagnostic test returns a good status.

But... When I run the "Change Windows Sounds" app and try to play the test tones, I receive the message "Failed to play test tone." The sound works fine while casting, and I imagine it would work fine for HDMI as well. But not for internal speakers.

I appreciate your reply. I tried to give you a thumbs up, but it wouldn't allow me to. I should have explained, I have been working on this problem for over a week. It happened just after I reset the notebook by redownloading and installing Windows 11. The sound had been working well before this. I tried to reload Windows without erasing all my local files, but it would not work -- I could only boot Windows in Safe Mode. I finally "bit the bullet" and did a clean download and install. When I first did that, the audio was working. Just about 15 minutes later, Windows did an automatic update, and the audio quit working and I could no longer adjust the brightness of my display.

I have gone through all the troubleshooters both from HP and from Microsoft. They all indicate no problems. I ran the UEFI hardware tests and found that the sound card and the speakers do, in fact, work. They played the test tone perfectly.

But once I start Windows again, there is no sound. When I pull up Control Panel > Sound, it shows the Realtek Audio Speaker and it is selected as default. It also shows a Realtek audio for headphones and that are unplugged. If I right-click on the speaker icon and select Test, I get an error message that says "Failed to play test tone".

I made this series of test tones and sine sweeps to help a member set up his system. I figured since I went to the trouble of packaging these and uploading them, I would share these with everyone. These will work great for setting up your system, adjusting crossover points, setting EQs, and determining how flat the system really is (using the final series of sweeps)... oh yeah, and just for showing off, if you so choose . All are unclipped 0db signals. I have enclosed the track list in a wordpad file, and I will include it here for you to determine if this set is for you.

This is saved on rapidshare, uncompressed in .wav format. It is under 100mb so you do not need a premium account to download it. DO NOT COMPRESS THIS FILE TO AN MP3!!! You may convert this to any lossless format, including, but not limited to .flac, .ape, and .wmp. Compressing these tones will result in incorrect settings, as lossy formats will not maintain all the required information. If you are not sure what formats can and can't be used, please ask here or PM me directly.

Uncompressed audio as stored on an audio-CD has a bit rate of 1,411.2 kbit/s, over 4 times that of a 320 kbit/s MP3. Does this mean it is 4X as loud? Of course not. I am not sure what exactly it is you are trying to achieve with this one sided challenge of the difference in quality between an uncompressed format vs a compressed format.

When music is compressed, most the information lost isn't audible to the human ear (as long as we are talking >192kbps). Compression removes unnecessary parts of the spectrum in sound. You must not know exactly what you are talking about. These lossless test tones are going to be EXACTLY the same as 320 (constant or v0) compressed test tones. If you can hear an audible difference, then you got some pretty amazing ears.

With too low a bit rate, compression artifacts (i.e. sounds that were not present in the original recording) may be audible in the reproduction. Some audio is hard to compress because of its randomness and sharp attacks. When this type of audio is compressed, artifacts such as ringing or pre-echo are usually heard. A sample of applause compressed with a relatively low bit rate provides a good example of compression artifacts. 17dc91bb1f
