Ripping CDs with FLAC - Best Compression Settings

Filed under
HowTos

As storage space becomes cheaper, there's a growing trend to save digital music files in a lossless format. Such lossless formats provide an exact replication of the audio quality found in the original content, usually on CD. The resulting files are also much larger, when compared to MP3 or AAC at 128kbps or 256kpbs. A favourite open source lossless audio codec is FLAC, which stands for Free Lossless Audio Codec. Within the possible FLAC settings there are 8 levels of compression to choose from when creating new files.

We decided to test which of the FLAC compression settings provided the best trade-off between final file size and encoding time. Higher compression will require more time, but should produce smaller file sizes.

Trying to mimic how we would actually go about ripping a whole CD, we decided to use the Ripit utility, and follow instructions posted on the Debian forum. Ripit is a great example of a truly useful utility where a fancy GUI is just not needed. Edit one simple configuration file, then type "ripit" at the command prompt and that's almost all there is to it.

  • An Open Source Load Balancer for OpenShift
    A highly-available deployment of OpenShift needs at least two load balancers: One to load balance the control plane (the master API endpoints) and one for the data plane (the application routers). In most on-premise deployments, we use appliance-based load balancers (such as F5 or Netscaler).
  • Red Hat Beefs Up Platform as a Service Suite
    Red Hat has begun shipping Red Hat Fuse 7, the next major release of its distributed, cloud-native integration solution, and introduced a new fully hosted low-code integration platform as a service (iPaaS) offering, Fuse Online. With Fuse 7, the vendor says expanding its integration capabilities natively to Red Hat OpenShift Container Platform, an enterprise Kubernetes platform. Fuse gives customers a unified solution for creating, extending and deploying containerized integration services across hybrid cloud environments.

  • The GPL cooperation commitment and Red Hat projects
    As of today, all new Red Hat-initiated open source projects that opt to use GPLv2 or LGPLv2.1 will be expected to supplement the license with the cure commitment language of GPLv3. The cure language will live in a file in the project source tree and will function as an additional permission extended to users from the start. This is the latest development in an ongoing initiative within the open source community to promote predictability and stability in enforcement of GPL-family licenses. The “automatic termination” provision in GPLv2 and LGPLv2.x is often interpreted as terminating the license upon noncompliance without a grace period or other opportunity to correct the error in compliance. When the Free Software Foundation released GPLv2 in 1991, it held nearly all GPL-licensed copyrights, in part a consequence of the copyright assignment policy then in place for GNU project contributions. Long after the Linux kernel and many other non-GNU projects began to adopt the GPL and LGPL, the FSF was still the only copyright holder regularly engaged in license enforcement. Under those conditions, the automatic termination feature of GPLv2 section 4 may have seemed an appropriate means of encouraging license compliance.

Red Hat changes its open-source licensing rules

From outside programming circles, software licensing may not seem important. In open-source, though, licensing is all important. So, when leading Linux company Red Hat announces that -- from here on out -- all new Red Hat-initiated open-source projects that use the GNU General Public License(GPLv2) or GNU Lesser General Public License (LGPL)v2.1 licenses will be expected to supplement the license with GPL version 3 (GPLv3)'s cure commitment language, it's a big deal.
