![]() The time-stretching engine is based on state-of-the-art psychoacoustic models and signal processing theory. ELASTIQUE PRO is based on a completely new approach to time-stretching, making stretching artifacts obsolete and thus providing sharp transients and crystal clear vocals without phasing artifacts. ELASTIQUE PRO offers stable timing, inter-channel phase coherence and sample accurate stretching. All three of them are able to run in realtime.ĮLASTIQUE PRO is a general purpose time-stretching engine that offers unmatched quality and easily fulfills the high quality demands of professional productions and broadcast applications. Zplane's ELASTIQUE family offers three different time-stretching (aka time-scaling, master tempo or key lock) and pitch shifting (aka pitch scaling or key lock) engines, optimized for different use cases: ELASTIQUE PRO, ELASTIQUE EFFICIENT, and ELASTIQUE TUNE. Zplane's AUFTAKT beat tracking SDK seamlessly integrates with BARBEATQ, but the algorithm can also be provided with beat information from a different source such as a fixed beat grid.īARBEATQ is an offline process which means it requires the complete audio file as input and outputs the cue point sequence result only after the file has been processed in its entirety. With beat information the results are on a higher level and always beat and bar synchronized and thus more useful for musical and DJ application. ![]() Without beat information there will be many more cue points and corresponding regions with varying timing precision. It analyzes the content of a music signal and outputs a sequence of time stamps identifying the most prominent changes in the audio. BARBEATQ furthermore compares the regions between the cue points and groups the most similar regions.īARBEATQ can be used in two different modes: Without and with extra beat information. Possibility to set multiple correction points for improved tracking.īARBEATQ provides automatic cue point detection.Ability to track time signature and time signature changes.Highly improved tempo detection and beat tracking ability.AUFTAKT v4 has improved detection rates by more than 30% across all genres, and even more than 40% on complex jazz music compared to its previous versions.ĪUFTAKT is able to track tempo variations and changes as well as time signature changes. The network has been trained with various music ranging from western pop music to classical and even ethnical music as well as single loops and guitars in order to broaden the range of trackable music stlyes. Other than previous implementations AUFTAKT v4 relies on deep neural networks and state of the art statistical models to take beat tracking to a new level. ID-Tags) and several other areas of application. Tempo and beat location information are useful for playlist generation, beat matched mixing, for automatic generation of high-level meta data information (e.g. Furthermore, the location of the beats is detected (beat grid). Show more Show lessĪUFTAKT is an automatic BPM (beats per minute) detection recognizing the tempo of any audio input signal. The second snipped again contains the same performances but with the second performance automatically aligned to the first. The first snippet contains the original two performances, each in one audio channel. ![]() This example demonstrates the alignment of two classical string quartet performances. The following synthesis step then applies the high quality élastique Pro time stretching to the one of the signals resulting of perfectly synchronized signals. After calculating the similarity in the four different domains between the two audio files, the relative tempo changes over time are extracted by finding the most likely solution given the similarity measure. Vice versa, different performances of the same piece of music might not be very similar in the Timbre-domain. This allows very flexible uses: while the pitches might differ between the lead vocal and the backing vocal line, they can be very similar with respect to loudness envelope and note onset times.
