A modern, self-hostable web spectrogram analyzer for your music library.

AudioDeck is a self-hosted web application that lets you visually analyze the audio quality of your music files. Think of it as a web-based, modern version of the classic Spek spectrogram analyzer.

Perfect for checking if your "high-quality" FLAC files are genuine or just upconverted low-quality MP3s.

jq for binary formats - tool, language and decoders for working with binary and text formats.

fq is inspired by the well known jq tool and language and allows you to work with binary formats the same way you would using jq. In addition it can present data like a hex viewer, transform, slice and concatenate binary data. It also supports nested formats and has an interactive REPL with auto-completion.

It was originally designed to query, inspect and debug media codecs and containers like mp4, flac, mp3, jpeg. But has since then been extended to support a variety of formats like executables, packet captures (with TCP reassembly) and serialization formats like JSON, YAML, XML, ASN1 BER, Avro, CBOR, protobuf. In addition it also has functions to work with URL:s, convert to/from hex, number bases, search for things etc.

MP3FS is a read-only FUSE filesystem which transcodes audio formats (currently FLAC) to MP3 on the fly when opened and read. This was written to enable me to use my FLAC collection with software and/or hardware which only understands the MP3 format e.g. gmediaserver to a Netgear MP101 MP3 player.
