This maybe can be improved by using bigger blocks during the compression step, but will need more memory for the process. The Reloaded version improves notably the CDDA compression ratio thanks to the FLAC compression, but is similar to the Original ECM Tool + 7zip if the image doesn't contains any CDDA track (it is even a bit worst). The compression ratio if LZMA compressor was improved by the Original ECM Tool thanks to the removed data. Reloaded conversely removes the GAP data, so reduction ratio is improved a bit.Ībout the compressed versions, the 7zip standalone compression is as expected the worst of all. The CDDA tracks in Firebugs have caused a poor reduction ratio in original ECM tool because it keeps all the sectors. This tests were made using the original ECM tool made by Neill Colett, this ECM Tool Reloaded without compression (just EC removal), 7zip extreme compression, Original ECM tool + 7zip extreme compression and this ECM Tool Reloaded using its internal compression method (LZMA for data and FLAC for audio, both in extreme compression mode).Īs you can see, the ECM Tool Reloaded uncompressed size is improved a bit by removing more data and dummy sectors from the streams. This make possible to use FLAC compresison in an Audio stream, which compress much more than other compression methods like LZMA or ZLIB.
ECM Tool Reloaded is also able to detect the stream type. In the v2 versions, internal compression was added and then external tools are not required anymore. This tool is completely loossless, so original data can be recovered without problems. This will allow to read the data from it very fast, and also can be complemented with a compression tool like 7zip to reach higher compression ratios. This ECM Tool allows you to remove all recoverable data from CD-ROM sectors, reducing the image size about 20% without using compression (depending of sectors types). ** I recommend to use the latest version, because old versions can contains bugs or incompatible features ** Description
