DY Baba Metzia
The Daf Yomi version is one sound file per daf, about 20-24 minutes long.
Every word of the Gemara is read, translated and explained clearly inside, with Rashi weaved into the explanation.
Used by both beginners and Roshei Yeshivos.
Especially effective for Daf Yomi preparation and review and to “catch up”, if one fell behind.
