Based on any audio sample, the shape of the design represents the audio waveform.
If there is one iconic SoundCloud emblem, recognized on-site and off, it is the playback waveform.
ENGADGET: Editorial: the new SoundCloud is optimized for listeners, not uploaders
Depending on the verbosity of the comment and its position on the waveform, the entire comment might not be visible.

It's like 'inverting' the signal on odd lines, or shifting it in time by 180 degrees of the color waveform frequency.

For instance, a waveform optimized for satellite uplinks looks different on an oscilloscope than one optimized for communicating with nearby tactical radios.
FORBES: New Radio Could Revolutionize Combat for U.S. Forces
Abandoning the "list" aspect, all tracks in a set are now bundled into a single waveform, which is presented just like a single track.

However, a recent meeting of federal officials and contractors in the capital found the wideband waveform is stabilizing and still essential to the overall communications architecture.

The technology at issue relates to how the data from a phone call is extracted from the carrier waveform that is received by a standard cell phone.

Notably, a new "Freeze" mode stops the waveform from galloping on, letting you tend to cue points, loops etc or slice it into samples for "playable" parts.
Dr. Gregory Chavat decided to give us a glimpse of an EM waveform, however, by using a coffee can radar system, a couple of LEDs, and long-exposure photography.
Comments are still embedded into the waveform with user icons.

SoundCloud allows us to embed those sound files right on WhiteHouse.gov, and users on SoundCloud can leave time-specific comments right in the waveform (the visual representation of the sound file).
One item in particular the wideband networking waveform has been a source of continuous frustration because its long gestation has delayed progress on all variants of the radio designed to host that signal.

Users connect their audio source to the player via analog audio input, and the player compares 15 seconds of waveform data with its internal "FingerPrints" database, matching the song up with its corresponding information from MusicID.

The most unique thing about Soundcloud is the way it displays the songs in waveform, allowing the user to listen to certain pieces or even stop and comment on specific points of a track (timed comments).
If you were to look at a waveform where you see how speech gets louder and quieter across time, the time between those peaks happens at a fairly predictable frequency of 3Hz to 8Hz across different languages.
Designed by the same team as the full-fat version, aspiring DJs can enjoy two waveform-based decks, with three-band EQ, eight effects (ported over from Trakor Pro) all redesigned from the ground up for the iPad's touch-based input.
Amazon Mechanical Turk used to be a popular one, but now a number of independent sites are around, such as Death by CAPTCHA. Clever hacks have even been developed for audio CAPTCHAs that merely deconstruct waveform shapes to identify what numbers are being spoken.
