Web Audio Conference 2019 - Deadline Extended

by Gerard Roma

*Apologies for cross-postings* Dear All, Due to popular demand, we extended the deadline for submissions to this year's Web Audio Conference. New abstract submission deadline: June 23, 2019 Submissions can be edited until: June 30, 2019 The updated call can be found below. Best wishes, The WAC 2019 Committee --- # Fifth Annual Web Audio Conference - 3rd Call for Submissions https://www.ntnu.edu/wac2019 The fifth Web Audio Conference (WAC) will be held 4-6 December, 2019 at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. WAC is an international conference dedicated to web audio technologies and applications. The conference addresses academic research, artistic research, development, design, evaluation and standards concerned with emerging audio-related web technologies such as Web Audio API, Web RTC, WebSockets and Javascript. The conference welcomes web developers, music technologists, computer musicians, application designers, industry engineers, R&D scientists, academic researchers, artists, students and people interested in the fields of web development, music technology, computer music, audio applications and web standards. The previous Web Audio Conferences were held in 2015 at IRCAM and Mozilla in Paris, in 2016 at Georgia Tech in Atlanta, in 2017 at the Centre for Digital Music, Queen Mary University of London in London, and in 2018 at TU Berlin in Berlin. The internet has become much more than a simple storage and delivery network for audio files, as modern web browsers on desktop and mobile devices bring new user experiences and interaction opportunities. New and emerging web technologies and standards now allow applications to create and manipulate sound in real-time at near-native speeds, enabling the creation of a new generation of web-based applications that mimic the capabilities of desktop software while leveraging unique opportunities afforded by the web in areas such as social collaboration, user experience, cloud computing, and portability. The Web Audio Conference focuses on innovative work by artists, researchers, students, and engineers in industry and academia, highlighting new standards, tools, APIs, and practices as well as innovative web audio applications for musical performance, education, research, collaboration, and production, with an emphasis on bringing more diversity into audio. ## Keynote Speakers We are pleased to announce our two keynote speakers: Rebekah Wilson (independent researcher, technologist, composer, co-founder and technology director for Chicago’s Source Elements) and Norbert Schnell (professor of Music Design at the Digital Media Faculty at the Furtwangen University). More info available at: https://www.ntnu.edu/wac2019/keynotes ## Pre-submission Draft Feedback Given that this year's conference theme is Diversity in Web Audio, we would like to welcome everyone to submit. We have launched a pre-submission draft feedback process to make people feel more confident, supported and welcome regarding submitting. This call is addressed to those individuals who are independent from academic institutions (deadline: June 9, 2019).

[ANN] Qtractor 0.9.8 - Yet Another Spring'19 Release

by Rui Nuno Capela

Hi all, Too hot to make any boring introduction, so let's get this straight: Qtractor 0.9.8 (spring'19) is released! The changes for this yet another seasonal release are as follows: - Plugin-lists and respective plugins state may now be exported and/or imported as XML files. - When in Drum Mode, Key and Scale are meaningless and thus functionally disabled from the MIDI clip editor (aka. piano-roll). - MIDI clip editor's View > Ghost Track menu option is now finally a reality: show any existing MIDI track and its respective clips in the background as dimmed, semi-transparent aka. ghost events. - Minor update to Debian packaging control file. - Make sure partially selected clips are reset to whole when Shift/Ctrl keyboard modifiers are in effect, to prevent extraneous clip splits or cutaways afterwards. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Resampling: SOX vs FFmpeg

by Louigi Verona

Hey everyone! I need advice on resampling. To give you context, I am working at SoundCloud, and one of the current projects is to refactor the transcoding pipeline. And proper resampling tools is a question that keeps coming up. One of the pipelines takes the uploaded file and transcodes it into an mp3. The general idea is to convert the original file to wav, resample it to 44100, and then finally convert it to mp3 using LAME. There are several questions here. 1. Which tool to use for transcoding. Should it be SoX, or FFmpeg, or something else? A lot of the info out there seems to favor SoX, but a lot of that info is pretty old. 2. Does it make sense to resample to 44100 or to 48000? If it were opus, the answer if simple: 48000, because that's what the opus spec actually recommends. There is no such recommendation for mp3 files. Also, upsampling is not an innocent procedure and the converter has to be of high quality as well. p.s.: the described pipeline is not the only one, the original file is transcoded into multiple formats, including formats with 48000 sample rate, but the one I am asking about focuses specifically on producing an mp3.
