2015-09-07player: add "queue cat" command
This will dump the contents of the current queue, including positional seeking information and commands. This is mainly intended for debugging and tools which rely on dtas internals.
2015-09-06use a common /dev/null
This allows us to avoid wasting time reopening the same device over and over again.
2015-07-18parse_freq: trivial new module for parsing frequencies
Seems a bit stupid, but oh well.
2015-07-18parse_time: pass through numeric types
This makes it easier to use in a user-friendly scripting interface we have coming up.
2015-06-16favor recv and recv_nonblock over recvmsg variants
We never use the full return value of the recvmsg* methods, so those allocations are wasted.
2015-06-15splitfx: set OUTFMT correctly for subenv if command is set
2015-05-24splitfx: allow -p/--sox-pipe option
This allows splitfx YAML files to operate more seamlessly with external commands such as play(1) especially when combined with the -t/--trim option.
2015-05-21splitfx: simplify output display
No point in executing echo and wasting CPU cycles. We'll only waste cycles now during dry-runs
2015-05-20splitfx: documentation for subclasses
2015-05-20splitfx: drop unnecessary variable
We no longer use it since commit 7b47191aa4c88b3daa4c980013f0047cb7ae7f6d ("splitfx: avoid double-truncation with user command")
2015-05-19source/splitfx: allow watching extra external scripts
Since writing nested shell commands inside YAML is subject to all sorts of strange quoting rules, encourage users to rely on external scripts which the YAML file refers to instead. These scripts can be written in any reasonable scripting language capable of executing other commands. This allows transparently monitoring things such as `my-script.rb' in the below example when playing my-splitfx.yml via dtas-player: --------------------- my-splitfx.yml ----------------------- infile: input.flac command: $INDIR/my-script.rb "$INFILE" ... --------------------- my-script.rb -------------------------- #!/usr/bin/ruby require 'shellwords' infile = ARGV.shift ch = %W(sox #{infile} -p).concat((ENV['TRIMFX'] || '').shellsplit) fx = %W(highpass 25 gain 9) l = ch.dup.concat(%W(remix 1v1)).concat(fx).concat(%w(contrast 30)) r = ch.dup.concat(%W(remix 2v1)).concat(fx).concat(%w(contrast 0)) cmd = %W(sox -M |#{l.shelljoin} |#{r.shelljoin}) cmd.concat((ENV['SOXFMT'] || '-p').shellsplit) cmd.concat(%w(- stats)) warn cmd.inspect exec *cmd
2015-05-19splitfx: avoid double-truncation with user command
It's probably harmless as the sub (second) command is usually innocuous as fars a modifying dynamic range, but it makes the command-line output confusing.
2015-05-18splitfx: remove support for encoding opus
Lossy file encoding has too many tunable variables and it is not a good fit for an audio production tool such as dtas-splitfx. This was becoming a maintenance burden for me and is a sign of featuritis.
2015-05-18splitfx: show correct command for output
2015-05-17process: implement array expansion to preserve spaces
This can make it easier to specify mcompand parameters in socks, as those require separate levels of parameter parsing and require quoting in shell.
2015-05-17dtas-splitfx: support --trim argument
It can often be useful to expose only part of a track for quick inspection. This lets us do that.
2015-05-17use monotonic clock on Ruby 2.1+
The monotonic clock is immune to stepping adjustments so it is more suitable for tracking elapsed time differences. Process.clock_gettime also generates less garbage on 64-bit systems due to the use of Flonum.
2015-05-10splitfx: fix non-generic, user-specified targets
Regression appeared in the previous commit, oops. commit ab63c7bb1b69423f8c39a60dd00230c560eecfc4 (splitfx: fix lossy output with player command is in use)
2015-05-10splitfx: fix lossy output with player command is in use
We must ensure lossy encodings do not get lossily-encoded twice, only once at the final stage. There is no effect for lossless outputs as lossless is the common case for splitfx users.
2015-05-10splitfx: --bits and --rate for quick-n-dirty generic targets
generic targets (e.g. "wav") is useful for quickly checking if clipping is introduced by dither and resampling, so we'll support changing the sample rate and bits-per-sample from the command-line so users don't need to setup their own targets or wait on FLAC encoding.
2015-05-10splitfx: pass compression factor to sox(1)
This can be useful for speeding up splitfx during development, as sox defaults to maximum compression with FLAC and that is extremely slow.
2015-05-10splitfx: support -O/--outdir switch to control output dir
It is useful to force output to a writable directory if the YAML file is on a read-only mount point or to force the output to a large tmpfs mount point to avoid SSD/HDD wear.
2015-05-10splitfx: fix typo for dither application
We do not need to dither unless we output to 16-bit or less. This bug caused us to unnecessarily apply dither on 24-bit output files. Oops!
2015-05-10tracklist: fix inf loop on ENOENT with repeat==1
If a file is missing, we must not respect the repeat option set by the user to avoid infinite looping
2015-05-07replaygain uses the "gain" effect instead of "vol"
The `gain' effect seems superior as it can "see" across the effects chain to take into account extra/lost headroom. For example, this allows me to add the the "gain -h" effect at the start of my effects chain before the RGFX placeholder in my source command, so when I play a file requiring a -6dB ReplayGain adjustment, I will only need an additional -4dB of headroom to accomodate the 10dB boost at 20Hz I use (for listening through headphones): Before: RGFX='vol -6dB' sox "$INFILE" $SOXFMT - $TRIMFX $RGFX vol -10dB equalizer 20 0.7071q 10 After: RGFX='gain -6' sox "$INFILE" $SOXFMT - $TRIMFX gain -h $RGFX equalizer 20 0.7071q 10
2015-04-13cleanup: avoid redundant Array conversion for escapes
We already convert xs arg to be an Array, so avoid bloating our code with redundancy.
2015-04-13escape INFILE and related environment variables
We may expand them, so ensure they're properly escaped, first for use in shell snippets.
2015-04-13xs: allow taking a string as input
This allows us to avoid unnecessary Array conversions in call sites
2015-02-13source/common: document dst_zero_byte attr
For seeking, the name might be a little confusing, but this is zero relative to the current queued source.
2015-02-04buffer: allow limiting the amount of bytes output tfx-pu
This will aid in allowing us to create effects which affect only a certain part of a track.
2015-02-04buffer/splice: prepare for IO::Splice::WAITALL removal
This feature in the io_splice was probably a bad idea and slated for removal at some point in the future. Anyways, do not rely on it since it is undocumented.
2015-02-04fadefx: effects chain generation
We need to generate a coherent command set for wrapping portions together, this sets us up for that.
2015-01-28player: fix queue skipping on player errors
Oops, introduced in the previous commit: commit 37eae22446feb5a805d9cd59f6ad54362829189f (player: support the "trim" parameter)
2015-01-28player: support the "trim" parameter
This feature is intended to allow users to "zoom-in" on a particular portion of a track to tweak parameters (either with dtas-sourceedit(1) or via playback of splitfx YAML files). This may be combined with looping the tracklist (via "tl repeat").
2015-01-25use omap (ordered map) for env hashes
While the Ruby Hash class is ordered in 1.9+, the YAML specifications do not specify hashes as ordered by default. Thus we must explicitly declare ordering via !omap for interopability with non-Ruby tools. This makes the YAML output of dtas-sourcedit and dtas-sinkedit slightly more verbose Users of dtas-splitfx are also encouraged to declare !omap when creating their YAML files for interoperability. Ordering env is important because any implementation of built-in variable expansion is dependent on it.
2015-01-23watchable: simplify check
@on_readable is always set, so there's no point in checking it again when we need to call it.
2015-01-20rename the TrimFX class to TFX
TrimFX was too ambiguous with the common environment variable we use throughout dtas. Since TFX is more limited in scope but should be more frequently-typed by users (of -splitfx) we'll use the shorter name here.
2015-01-20doc: describe most classes a bit
Hopefully this makes the code less daunting to newcomers
2015-01-20drop Rubinius workaround
I'm done with dealing with proprietary bug trackers.
2015-01-19update copyright years and links to mailing list archives
The documentation part is managed by the new Documentation/update-copyright script. For the future, the rest may be managed by the update-copyright tool in gnulib
2015-01-19Revert "fadefx: remove module"
This reverts commit 3471463325be6c990b3abd18b4d34f723440d19a. While not strictly necessary, it makes the user syntax in splitfx files much terser. Changes from the original version should make it easier-to-read and the diagram should help a lot with understanding.
2015-01-19consolidate spawn fix for Ruby [Bug #8770]
Ensure we can apply the workaround to dtas-sourceedit and our test cases while also simplifying the existing call sites a little. This will also make for less code churn in 3-5 years down the line when we drop <= 2.1 support.
2015-01-19avoid aliasing global "spawn" method
This makes debugging, grepping, and following code confusing at times and also unexpected breaks usage of the global "spawn" method.
2015-01-19splitfx: export TBEG and TLEN variables
These are the raw sample counts for the "trim" effect and may be useful for arithmetic in the shell.
2015-01-19sinkedit: flesh out all parameters
dtas-sinkedit now shows default parameters in addition to user-changed parameters, allowing easier editing. Also, we need to be able to revert back to using the default pipe_size on Linux by setting pipe_size to nil (as an empty field in YAML).
2015-01-19dtas-sourceedit: update player as user saves in the editor
This allows changes in the source YAML file to be reflected immediately in player after the user saves the file in their favorite $EDITOR. Previously, a user would need to: 1) start dtas-sourceedit, spawning $EDITOR 2) edit the file 3) save changes 4) exit $EDITOR 5) repeat starting from 1) until happy with the results Now, the workflow allows avoiding the context switch between their $EDITOR and terminal to restart dtas-sourcedit: 1) start dtas-sourceedit, spawning $EDITOR 2) edit the file 3) save changes 4) repeat starting from 1) until happy with the results 5) exit $EDITOR In my experience, this greatly speeds up tuning of the playback change, giving all the repeatability and flexibility of editing text files while having the immediacy of an interactive UI. Keep in mind this can cause problems for those with auto-save enabled in their $EDITOR buffer at inopportune times, so a -N/--no-watch option is added.
2015-01-19splitfx: remove unnecessary assignment
We already assigned fmt before entering the case statement, so make the case statement smaller.
2015-01-06player: enqueued commands cannot use bypass
We cannot specify an audio format for bypass mode, so inherit the last one we used and hope it works.
2015-01-03splitfx: remove redundant Hash#merge call
This was unnecessary since we already iterate through the overrides hash and merge "manually" based on command-line arguments (which allows us to represent nested hashes).
2015-01-03dtas-splitfx: use the top-level command used by -player
If somebody is using dtas-player to help edit a file for dtas-splitfx, it is likely they will want to use it when generating the final files (regardless of "target" format).
