Ableton detune vs transpose12/19/2023 ![]() In this case, if the Warp mode ( see 9.3) of the Clip is set to Beats, Tones, Texture or Re-Pitch (but not Complex or Complex Pro), playback will be neutral. If the tempo of a Clip is the same as the tempo of the Set, that clip will play back unstretched. Please note that “playback“ in this context refers only to the audio within Live, prior to the point at which it reaches your audio hardware.ģ4.2.3 Unstretched Beats/Tones/Texture/Re-Pitch Warping This is verified by cancellation tests of rendered output. ![]() Playback of an unstretched audio file in Live is a neutral operation, provided that the file‘s sample rate is the same as that set in Live‘s Preferences and that the file is played back without transposition. rendering to a file with a lower bit depth than the original results in the smallest amount of distortion possible within a 32-bit system.ģ4.2.2 Matching sample rate/no transposition.rendering to a file with a higher bit depth than the original results in complete phase cancellation.rendering to a file with the same bit depth as the original results in complete phase cancellation.Phase cancellation testing of the original and output files shows the following: Live‘s rendering performance is tested by loading three types of unprocessed audio files (white noise, fixed-frequency sine waves and sine sweeps) in 16-, 24- and 32-bit word lengths and rendering these to output files, also with varying bit resolutions. no non-neutral operations have been applied.the sample rate of the rendered file is the same as that set for the audio hardware in Live‘s Preferences.Rendering is a neutral operation under certain conditions: The Export Audio/Video ( see 5.2.3) command renders Live’s audio output to a file on disk. Even a gain change is, technically, non-neutral. So any neutral operations that occur after it will, of course, still result in audio that is altered in some way. For example, running an audio signal through an effects device is a non-neutral operation. The list of neutral operations found below is provided primarily as an abstract reference while all of these operations are, in fact, neutral, it is important to remember that each of them may (and almost certainly will) occur within a context that also contains non-neutral operations. Applying neutral operations to files being exported from Live ensures that the quality of your output file will be at least as high as what you heard during playback. Applying neutral operations to files imported into Live ensures that the imported audio will be identical to the files saved on disk. Applying neutral operations to audio that was recorded into Live ensures that the audio will be unchanged from the point of analog-to-digital conversion. You can be sure that using these functions will never cause any signal degradation. Procedures in Live that will cause absolutely no change in audio quality are referred to as neutral operations. We add additional tests as we add features, and we will never release an update unless it passes every test. Rather, it is a summary of measurable facts about what Live actually does under various conditions.Īs of this writing, every version of Live is subjected to a suite of 473 automated tests that cover every aspect of Live‘s functionality. ![]() Furthermore, this paper makes no claims about how Live compares to other audio software. We make no claims about what you can hear because we can‘t possibly predict the variables that make up your listening environment, audio hardware, hearing sensitivity, etc. We have also written this fact sheet to help users understand exactly how their audio is (or is not) being modified when using certain features in Live that are often misunderstood, as well as tips for achieving the highest quality results.Īs mentioned above, the focus of our research has been on objective (that is, quantifiable and measurable) behavior. As a result of this testing, we have implemented a number of low-level improvements to the audio engine. Prior to the release of Live 7, much of Ableton‘s development effort was focused on carefully and objectively testing Live‘s fundamental audio performance.
