Here is the complete list of all command line utilities included in the present package: gsm-amr2efr See AMR-EFR-conversion article. gsm-efr2amr gsmefr-cod-parse See EFR-testing article. gsmefr-dec-parse gsmefr-decode See Codec-utils article. gsmefr-decode-r gsmefr-encode gsmefr-encode-r gsmefr-dlcap-dec See Calypso-TCH-downlink article. gsmefr-dlcap-gsmx gsmefr-dlcap-parse gsmefr-etsi-dec See EFR-testing article. gsmefr-etsi-enc gsmefr-rec2etsi This program reads an EFR session recording in gsmx format and converts it into ETSI decoder input (.dec) format. It was written early in the project as a sanity check, to verify that the format of TCH uplink from sysmoBTS in EFR mode matches our expectations, before embarking on the labor-intensive project to librify EFR reference code from ETSI. gsmfr-decode See Codec-utils article. gsmfr-decode-r gsmfr-encode gsmfr-encode-r gsmfr-dlcap-gsmx See Calypso-TCH-downlink article. gsmfr-dlcap-parse gsmfr-hand-test This program was written as part of a debug chase: there seemed to be a design flaw in libgsmfrp, but the actual bug turned out to be in the way we patched osmo-bts-sysmo to produce a continuous RTP stream. gsmfr-max-out Another test program written as part of the same debug chase. gsmfr-preproc This program reads a gsmx file in FR codec format, passes it through our Rx DTX preprocessor (libgsmfrp), and writes the preprocessor output to another .gsm file. gsmrec-dump See Binary-file-format article. pcm16-raw2wav See PCM-file-formats article. pcm16-wav2raw rtp-cont-check See RTP-analysis article. rtp-g711-extr rtp-gsmfr-extr rtp-jitter-view
