[linux-audio-user] Re: [ANN] FreeBoB 1.0 released - Firewire Audio for Linux

Greetings, Now that JACK 0.102.20 and QJackCtl 0.2.21 being released, the FreeBoB team is proud to present libfreebob 1.0. The FreeBoB project aims to provide a generic solution for using Firewire (semi-)pro-audio devices in Linux. This release provides support for the devices based on the BridgeCo DM1000 or DM1500 chipset that are running the BeBoB firmware. For a list of supported devices, consult our website at freebob.sf.net. FreeBoB currently provides an interface library that allows firewire audio devices to be used with the JACK audio server, using a dedicated backend. This backend is included in the official JACK releases, from this version on (i.e. 0.102.20). The latest version of QJackCtl also includes support for this FreeBoB backend. MIDI support is provided through ALSA sequencer. Feature list: * Automatic detection & configuration of devices. If there are multiple devices attached to the same firewire bus, freebob merges them into one big device. The devices have to be synced externally (wordclock/spdif) so that they don't drift. Note that this release cannot setup the boxes to be synced yet, being synced is a precondition at the moment. (I tested this with 2 phase88's connected with wordclock, and this works without the need for any special setting because the Phase88 automatically chooses wordclock slave when there is a wordclock signal present. This can be different for other models). * Audio I/O on all analog channels at all sample rates supported by the device. SPDIF/ADAT I/O works in most cases (when presented as analog IO by the device). AC3 passthrough doesn't work. * Midi I/O for all midi ports the device implements, using alsa-sequencer * Round-trip latency figures around 5ms (depends on system configuration). 10ms is achievable on all well-configured machines Not supported yet: * Hardware mixing ("zero latency" mixer) * Device-specific configuration (input gain switches, sync source selection, midi control mappings, ...) * ALSA for audio IO * Special SPDIF/ADAT stream support You can download FreeBoB 1.0 at our sourceforge page: http://sourceforge.net/project/showfiles.php?group_id=117802 more info at freebob.sf.net What's next? We are working on the second generation of the FreeBoB codebase. The 1.0 release is the endpoint for the codebase that dates back to the start of the project. The 2.0 codebase is a complete redesign of the system using 1.0 as a 'golden spec'. While the 1.0 version is BeBoB-only, the 2.0 codebase is designed as a framework to support all firewire based audio boxes. The current level of functionality is almost the same for both codebases. The main difference is that 1.0 had one year of testing and 2.0 doesn't, it's still in the alpha stage. Needless to say that 2.0 will outperform 1.0 by far ;). Of course this redesign isn't for the sake of aesthetic beauty or lack of things to do... I can announce that we are already working on broadening the supported device list. Currently there is support for the Motu Traveller and the Motu 828 (through reverse engineering). There are also contacts with the DICE-II developers to implement generic support for devices based upon their chipset. As an extra, support for Metric Halo devices is also in the pipeline. Once all of these devices are supported, we will cover a very large part of the Firewire audio device spectrum. The most important void will be RME Fireface support, and for the real budget users: Behringer and Hercules devices. That's all folks! Pieter Palmers (on behalf of the FreeBoB team)
