<p>In most examples of modern machine learning, ML practitioners use Python to design complex mathematical models that can be auto-differentiated and then optimized via stochastic gradient descent in order to maximize some objective. Audio engineers, however, don't use Python because it lacks the elegant syntax and powerful libraries of an audio domain-specific language (DSL) such as Faust. We present a pipeline which is one of the first of its kind to bridge the gap between a library-rich audio DSL and a powerful auto-diff ML framework. This Faust-to-<a href="https://jax.readthedocs.io/en/latest/">JAX</a> pipeline allows audio engineers to auto-differentiate DSP functions that would have been too time-consuming to re-implement in Python or difficult to differentiate manually. Once Faust code is converted to JAX, the XLA compiler produces well-optimized code that scales well in cloud-computing systems. We present several early experiments showing our pipeline's potential to optimize audio-related objectives.</p>

<h1 id="syfala">Bonus Event: Faust/FPGA Workshop<br>on Dec. 1, 2023 @ CITI Lab (Lyon)</h1>

<h2 style="margin-top: -2rem;"><i>Experimenting With the Faust to FPGA Compilation Flow Using Grid5000</i></h2>

<p style="font-size: 1.25rem;">The goal of this hands-on workshop is to learn the fundamentals of FPGA programming for real-time audio Digital Signal Processing (DSP) applications. It focuses on the Syfala toolchain: the first open-source audio DSP compiler targeting FPGAs using the Faust programming language.</p>

<p>Field-Programmable Gate Arrays (FPGAs) provide unparalleled audio latency and computational power. In many cases, they are a a better fit for real-time audio processing applications than "traditional" CPUs. These embedded platforms can easily handle audio DSP programs with hundreds of channels while guaranteeing very low latency. This allows for the design of systems with unmatched performances and unique features for spatial audio, noise cancelling, active control of room acoustics etc. However, programming FPGAs is very complex and out of reach to non-specialized engineers as well as to most people in the audio community. Syfala uses the Faust compiler as well as the Xilinx HLS tool to solve this issue and program Digilent Zybo FPGA boards. Given that Xilinx tools installation is very complex, we propose to use the Grid5000 platform which allows us to provide pre-configured remote machine with Xilinx tool and Syfala installed on them.

<p>This workshop is associated with PAW 2023 which takes place the following day.</p>

<p><b>PLEASE NOTE:</b> This workshop will imply non trivial hands-on tutorials including SSH connection to Grid5000. Please make sure to read the technical instructions and prerequisites below before registering. For any information please contact us (<a href="mailto:[email protected]">[email protected]</a>)</p>

<h3>Practical Information</h3>

<ul>
<li><b>Where:</b> INSA Lyon, Hedy Lamarr building, TD-C Room, 6 avenue des arts, Villeurbanne, France</li>
