TwoLAME TODO List
=================
- Fix bug with Padding and framesizes with samplerate of 44.1 and 22kHz
- use Exact-width integer types (eg uint16_t)
- Add libresample support to libtoolame (toolame_set_in_samplerate etc.)
- parameter checking in toolame.c using assert
- Create a new toolame.spec (be sure to include twolame.pc)
- quite a lot of duplicated code between toolame_encode_buffer_interleaved
and toolame_encode_buffer
- sort out changing parameter for toolame_set_VBR_q from FLOAT to int (like LAME)
- Add libresample support to libtwolame (twolame_set_in_samplerate etc.)
- parameter checking in twolame.c using assert
- Create a new twolame.spec (be sure to include twolame.pc)
- quite a lot of duplicated code between twolame_encode_buffer_interleaved
and twolame_encode_buffer
- sort out changing parameter for twolame_set_VBR_q from FLOAT to int (like LAME)
- better use of verbosity settings
- full options sanity checking/verification in toolame_init_params
- full options sanity checking/verification in twolame_init_params
- don't allow twolame_set_* after twolame_init_params() has been called

# lt~obsolete.m4 -- aclocal satisfying obsolete definitions. -*-Autoconf-*-
#
# Copyright (C) 2004, 2005, 2007, 2009 Free Software Foundation, Inc.
# Written by Scott James Remnant, 2004.

# This file is free software; the Free Software Foundation gives

# serial 5 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.

<div class="paragraph"><p>In MPEG audio encoding, a psychoacoustic model (PAM) is used to determine which
are the sonically important parts of the waveform that is being encoded. The PAM
looks for loud sounds which may mask soft sounds, noise which may affect the level
of sounds nearby, sounds which are too soft for us to hear and should be ignored
and so on. The information from the PAM is used to determine which parts of the
spectrum should get more bits and thus be encoded at greater quality - and which
parts are inaudible/unimportant and should thus get fewer bits.</p>

<div class="paragraph"><p>In MPEG Audio LayerII encoding, 1152 sound samples are read in - this constitutes
a <em>frame</em>. For each frame the PAM outputs just <strong>32</strong> values
(The values are the Signal to Masking Ratio [SMR] in that subband). This is important!
There are only 32 values to determine how to alloctate bits for 1152 samples - this
is a pretty coarse technique.</p>
<p>The different PAMs listed below use different techniques to decide on these 32

<div class="paragraph"><p>The different PAMs listed below use different techniques to decide on these 32
values. Some models are better than others - meaning that the 32 values chosen
are pretty good at spreading the bits where they should go. Even with a really
bad PAM (e.g. Model -1) you can still get satisfactory results a lot of the time.
All of these models have strengths and weaknesses. The model <em>you</em> end up using
will be the one that produces the best sound for your ears, for your audio.</p>

"Surprising" in that the other PAMs go to the effort of calculating FFTs
and subbands and masking, and this one does absolutely <strong>nothing</strong>.
Zip. Nada. Diddly Squat. This model might be the best example of why
it is hard to make a good model - if having no computations sounds OK,
how do you improve on it?</p>
<p><strong>Cons</strong>: Absolutely no attempt to consider any of the masking effects that
would help the audio sound better.</p>

<p>These PAMs are from the ISO standard. Just because they are the standard,

the MP3 standard psycho models and made their own (GPSYCHO).</p>

<title>Input File</title>
<simpara>twolame uses libsndfile for reading the input sound file, so
the input file can be in any format supported by libsndfile.
To read raw PCM audio from STDIN, then use - as the input filename.</simpara>
</refsect2>
<refsect2>
<title>Output File</title>
<simpara>If no output filename is specified, then suffix of the input filename
is automatically changed to .mp2. To write the encoded audio to STDOUT
then use - as the output filename.</simpara>

<term>
-s, --samplerate &lt;int&gt;
</term>
<listitem>

@ -34,7 +34,7 @@ A level of 5 works very well for me.
The level value can is a measurement of quality - the higher
the level the higher the average bitrate of the resultant file.

The confusing part of my implementation of LayerII VBR is that it's different from MP3 VBR.
