1 Introduction

Easy audio

Overview

Easy audio is my small but slowly growing pack of audio decoders. It can help you decode audio files and also provides easy access to metadata.

It has:

• FLAC format support. Can decode anything, supports almost all metadata blocks.
• Partial support for WavPack format. Can read and decode non-hybrid lossless WavPack data which is the most used, anyway. Support many metadata blocks (though they are not as useful as in FLAC).
• Partial wav container support, can read uncompressed, a-law compressed and mu-law compressed audio data.
• OGG container support, but, unfortunately, without Vorbis support. Can read FLAC compressed data inside OGG container.
• APEv2 tags support.

It has minimum dependencies (only flexi-streams for reading UTF-8 coded values from metadata) and written entirely in Common Lisp. It contains unsafe code to achieve maximal performance and assumes that fixnums are more than 32-bit wide, so I am not sure if it works on some 32-bit implementations or not.

5.1.3 Macros

Macro: defreader (NAME &optional DOCSTRING) (&optional MAKE-FORM OBJ-SYM) &rest SLOTS

Generate a reader function to read data from bit-reader into
an arbitrary object with accessor-like interface. NAME is the
name of such function. The new function will accept two
arguments: a bit-reader and an optional object to be
modified. If no object is passed, it will be created with MAKE-FORM. You can assign a symbol OBJ-SYM to newly created instance. Each slot from SLOTS is a list. It has the
following syntax:

(ACCESSOR (:BIT)|(:OCTETS n)|(:BITS n)|(:OCTET-VECTOR v) [:ENDIANNESS :BIG|:LITTLE] [:FUNCTION FUNC-NAME])

(ACCESSOR object) must be a ’place’ understandable for setf.
One and only one of BITS, OCTETS or OCTET-VECTOR must be
supplied. Endianness may be supplied and will be passed to low-level bitreader function. if FUNC-NAME is supplied,
readed value will be passed to this function and then
assigned to the slot.

UPD: If ACCESSOR is NIL, no data will be stored to anywhere,
but it will be read accordingly to specifications and then lost
for good.

If both OBJ-SYM is not given and MAKE-FORM is NIL, the bitreader itself will be returned from reader function.

Package

easy-audio.utils

utils/utils.lisp (file)

Macro: defvar-unbound VAR &optional DOC-STRING
